### What did you do?

Typing in [this `go.mod` file](https://github.com/walles/moar/blob/d71ce309d9a52f460393b7536b8113468013d649/go.mod).

On the `github.com/sirupsen/logrus` line, I deleted `v1.8.1` and typed just a `v` instead.

```
module github.com/walles/moar

go 1.16

require (
	github.com/alecthomas/chroma/v2 v2.4.0
	github.com/google/go-cmp v0.5.9
	github.com/sirupsen/logrus v1.8.1
	golang.org/x/sys v0.0.0-20210511113859-b0526f3d8744
	golang.org/x/term v0.0.0-20210503060354-a79de5458b56
	gotest.tools/v3 v3.3.0
)
```

### What did you expect to see?

Version number completions:
* `v1.9.0` (latest version as I'm typing in this issue)

### What did you see instead?

No completion, just the `v` that I typed.

### Editor and settings

`vscode.json`:

```json
{
  "go.useLanguageServer": true,
  "go.toolsManagement.autoUpdate": true,
  "go.lintTool": "golangci-lint"
}
```
