FE: BUG: Time dimension not recognized if units are not exactly ISO8601

# Problem

For the GOES16 layer in the SAT WMS, the following WMS dimension does not work properly. This is because the units property is not set correctly:

```xml
<Dimension name="time" units="NA" default="2022-03-23T10:55:06Z" multipleValues="1" nearestValue="0" current="1">2022-03-22T09:15:06Z,2022-03-22T09:25:06Z,2022-03-22T09:35:06Z,2022-03-22T09:45:06Z,2022-03-22T09:55:06Z,2022-03-22T10:05:06Z,2022-03-22T10:15:06Z,2022-03-22T10:25:06Z,2022-03-22T10:35:06Z,2022-03-22T10:45:06Z,2022-03-22T10:55:06Z,2022-03-22T11:05:06Z,2022-03-22T11:15:06Z,2022-03-22T11:25:06Z,2022-03-22T11:35:06Z,2022-03-22T11:45:06Z,2022-03-22T11:55:06Z,2022-03-22T12:05:06Z,2022-03-22T12:15:06Z,2022-03-22T12:25:06Z,2022-03-22T12:35:06Z,2022-03-22T12:45:06Z,2022-03-22T12:55:06Z,2022-03-22T13:05:06Z,2022-03-22T13:15:06Z,2022-03-22T13:25:06Z,2022-03-22T13:35:06Z,2022-03-22T13:45:06Z,2022-03-22T13:55:06Z,2022-03-22T14:05:06Z,2022-03-22T14:15:06Z,2022-03-22T14:25:06Z,2022-03-22T14:35:06Z,2022-03-22T14:45:06Z,2022-03-22T14:55:06Z,2022-03-22T15:05:06Z,2022-03-22T15:15:06Z,2022-03-22T15:25:06Z,2022-03-22T15:35:06Z,2022-03-22T15:45:06Z,2022-03-22T15:55:06Z,2022-03-22T16:05:06Z,2022-03-22T16:15:06Z,2022-03-22T16:25:06Z,2022-03-22T16:35:06Z,2022-03-22T16:45:06Z,2022-03-22T16:55:06Z,2022-03-22T17:05:06Z,2022-03-22T17:15:06Z,2022-03-22T17:25:06Z,2022-03-22T17:35:06Z,2022-03-22T17:45:06Z,2022-03-22T17:55:06Z,2022-03-22T18:05:06Z,2022-03-22T18:15:06Z,2022-03-22T18:25:06Z,2022-03-22T18:35:06Z,2022-03-22T18:45:06Z,2022-03-22T18:55:06Z,2022-03-22T19:05:06Z,2022-03-22T19:15:06Z,2022-03-22T19:25:06Z,2022-03-22T19:35:06Z,2022-03-22T19:45:06Z,2022-03-22T19:55:06Z,2022-03-22T20:05:06Z,2022-03-22T20:15:06Z,2022-03-22T20:25:06Z,2022-03-22T20:35:06Z,2022-03-22T20:45:06Z,2022-03-22T20:55:06Z,2022-03-22T21:05:06Z,2022-03-22T21:15:06Z,2022-03-22T21:25:06Z,2022-03-22T21:35:06Z,2022-03-22T21:45:06Z,2022-03-22T21:55:06Z,2022-03-22T22:05:06Z,2022-03-22T22:15:06Z,2022-03-22T22:25:06Z,2022-03-22T22:35:06Z,2022-03-22T22:45:06Z,2022-03-22T22:55:06Z,2022-03-22T23:05:06Z,2022-03-22T23:15:06Z,2022-03-22T23:25:06Z,2022-03-22T23:35:06Z,2022-03-22T23:45:06Z,2022-03-22T23:55:06Z,2022-03-23T00:05:06Z,2022-03-23T00:15:06Z,2022-03-23T00:25:06Z,2022-03-23T00:35:06Z,2022-03-23T00:45:06Z,2022-03-23T00:55:06Z,2022-03-23T01:05:06Z,2022-03-23T01:15:06Z,2022-03-23T01:25:06Z,2022-03-23T01:35:06Z,2022-03-23T01:45:06Z,2022-03-23T01:55:06Z,2022-03-23T02:05:06Z,2022-03-23T02:15:06Z,2022-03-23T02:25:06Z,2022-03-23T02:35:06Z,2022-03-23T02:45:06Z,2022-03-23T02:55:06Z,2022-03-23T03:05:06Z,2022-03-23T03:15:06Z,2022-03-23T03:25:06Z,2022-03-23T03:35:06Z,2022-03-23T03:45:06Z,2022-03-23T03:55:06Z,2022-03-23T04:05:06Z,2022-03-23T04:15:06Z,2022-03-23T04:25:06Z,2022-03-23T04:35:06Z,2022-03-23T04:45:06Z,2022-03-23T04:55:06Z,2022-03-23T05:05:06Z,2022-03-23T05:15:06Z,2022-03-23T05:25:06Z,2022-03-23T05:35:06Z,2022-03-23T05:45:06Z,2022-03-23T05:55:06Z,2022-03-23T06:05:06Z,2022-03-23T06:15:06Z,2022-03-23T06:25:06Z,2022-03-23T06:35:06Z,2022-03-23T06:45:06Z,2022-03-23T06:55:06Z,2022-03-23T07:05:06Z,2022-03-23T07:15:06Z,2022-03-23T07:25:06Z,2022-03-23T07:35:06Z,2022-03-23T07:45:06Z,2022-03-23T07:55:06Z,2022-03-23T08:05:06Z,2022-03-23T08:15:06Z,2022-03-23T08:25:06Z,2022-03-23T08:35:06Z,2022-03-23T08:45:06Z,2022-03-23T08:55:06Z,2022-03-23T09:05:06Z,2022-03-23T09:15:06Z,2022-03-23T09:25:06Z,2022-03-23T09:35:06Z,2022-03-23T09:45:06Z,2022-03-23T09:55:06Z,2022-03-23T10:05:06Z,2022-03-23T10:15:06Z,2022-03-23T10:25:06Z,2022-03-23T10:35:06Z,2022-03-23T10:45:06Z,2022-03-23T10:55:06Z</Dimension>

# Discussion

We can fix this in the backend or in the frontend (or both). The frontend could be made less strict. The backend could add the correct unit.

# Solution:

Make the frontend less strict for detecting the time dimension.

In https://gitlab.com/opengeoweb/opengeoweb/-/blob/master/libs/webmap/src/lib/components/WMJSDimension.ts#L246:

Change 

```
if (this.units === 'ISO8601') {
```
 to

```
if (this.units === 'ISO8601' || this.name === 'time') {
```

# How to test

The timeslider should have an effect on the GOES16 layer
