Integrate MinVer for Git-based versioning

Add MinVer 6.0.0 package for automatic version calculation from Git tags:
- MinVer automatically determines version from Git tags (e.g., v6.1.0)
- Generates proper semantic versions with pre-release identifiers
- Integrates with build height for automatic patch increments
- VersionPrefix (6.1.0) serves as fallback when no tags exist
- MinVerTagPrefix set to 'v' to match conventional tag format

Benefits:
- Eliminates manual version updates in project files
- Automatic versioning in CI/CD pipelines
- Proper pre-release versioning for feature branches
- Consistent with deterministic builds

Microsoft.SourceLink.GitHub is already at latest version 8.0.0.

Version calculation examples:
- On tag v6.1.0: produces version 6.1.0
- After tag: produces version 6.1.1-alpha.0.{height}
- On branch: includes branch name in pre-release identifier
