GitVersion 6.0.0 is not supported due to breaking changes

### Problem description

There are [breaking changes](https://github.com/GitTools/GitVersion/releases/tag/6.0.0) in GitVersion that fails builds in projects using Sampler. Workaround is to pin an older version.

Notable breaking changes are configuration properties that has changed name, and output properties (`NuGetVersionV2`) that no longer exist.

Configuration documentation: https://gitversion.net/docs/reference/configuration
Output variables: https://gitversion.net/docs/reference/variables

### How to reproduce

Build a project using GitVersion v6.0.0

### Expected behavior

Sampler supports v6.0.0

### Current behavior

Fails if GitVersion 6.0.0 is installeed.

### Suggested solution

Update all tasks and configuration (and templates) to use another property than `NuGetVersionV2`.

Did a quick test in another project to see what was needed when I realized that we have hardcoded `NuGetVersionV2` in the tasks. This PR shows the needed config changes: https://github.com/viscalyx/PesterConverter/pull/28

Also, the property used cannot contain '.' in the prerelease string since it is not supported in module manifest. 🤔

### 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
n/a
```

Start by reviewing the tasks, configuration, and templates for hardcoded GitVersion properties, especially NuGetVersionV2, then compare them with the linked GitVersion configuration and output-variable documentation. Reproduce a build with GitVersion 6.0.0 and confirm completion when the build succeeds and prerelease values are valid for the module manifest.
