fix(numberFilter): convert all non-finite/non-numbers/non-numeric strings to the empty string

The previous code for filtering out non-finite numbers was broken, as it would convert `null` to `0`,
as well as arrays.

This change fixes this by converting null/undefined/NaN/Infinity/any object to the empty string.

Closes #6188

most files but these are in the ng module but are stored at the root folder.

docs(bike-shed-migration): let markdown deal with extenal links

It is problematic to use {@link} tags with external links because the
markdown parser converts them to links for us before we parse the @links.
This means that the following tag:

```
{@link http://www.google.com Google}
```

get converted to:

```
{@link <a href="http://www.google.com/"></a> Google}
```

Our {@link} parser then converts this to:

```
<a href="<a">&lt;</a>href="http://www.google.com/"></a> Google}
```

which is clearly a mess.  The best solution is not to use {@link} tags
for external links and just use the standard markdown syntax:

```
[Google](http://www.google.com)
```

In the long run, we could look into configuring or modifying `marked` not
to convert these external links or we could provide a "pre-parser"
processor that dealt with such links before `marked` gets its hands on it.
