### How to reproduce

This code failed since it found a release tag (v5.0.0) but since the command returned more than one tag it got the wrong name for the branch so it failed there and stopped.

### Expected behavior

Not to fail the task.

### Current behavior

Task throws error.

### Suggested solution

This code need to have logic to handle multiple tags and understand that the highest release tag is more important than any preview tag.

https://github.com/gaelcolas/Sampler/blob/a14049c5241e75f52270d292c026d67dac173a92/.build/tasks/Create_Changelog_Branch.build.ps1#L182-L206

### Operating system the target node is running

```text
n/a
```

### PowerShell version and build the target node is running

```text
n/a
```

### Module version used

```text
latest
```

Start with .build/tasks/Create_Changelog_Branch.build.ps1 at lines 182-206 and inspect how the tags returned by git tag -l --points-at are used to form the branch name. Reproduce the case with multiple release and preview tags from the issue. Done means the changelog task does not fail and selects the highest release tag over preview tags.
