  ==============================================================
  Retrieves and exposes Git information.

  If the importing project has a C#, F# or VB Language property, by default a ThisAssembly file/class will be generated containing assembly-level metadata for the git information,
  as well as a ThisAssembly static class with constants for all the available values.

  Customization:

  $(GitVersion): set to 'false' to avoid setting Version and PackageVersion to a default version with format:
                 $(GitSemVerMajor).$(GitSemVerMinor).$(GitSemVerPatch)$(GitSemVerDashLabel)+$(GitBranch).$(GitCommit)

  $(GitThisAssembly): set to 'false' to prevent assembly metadata and constants generation.

  $(GitThisAssemblyMetadata): set to 'false' to prevent assembly metadata generation only. Defaults to 'false'.
                              If 'true', it will also provide assembly metadata attributes for each of the populated values.

  $(ThisAssemblyNamespace): allows overriding the namespace for the ThisAssembly class. Defaults to the global namespace.

  $(GitRemote): name of remote to get repository url for. Defaults to 'origin'.

  $(GitDefaultBranch): determines the base branch used to calculate commits on top of current branch. Defaults to 'main'.

  $(GitVersionFile): determines the name of a file in the Git repository root used to provide the base version info. Defaults to 'GitInfo.txt'.

  $(GitCommitsRelativeTo): optionally specifies an alternative directory for counting commits on top of the base version. Defaults to the $(GitVersionFile) directory.

  $(GitCommitsIgnoreMerges): set to 'true' to ignore merge commits when calculating the number of commits. Defaults to 'false'.

  $(GitInfoReportImportance): allows rendering all the retrieved git information with the specified message importance ('high', 'normal' or 'low'). Defaults to 'low'.

  $(GitIgnoreBranchVersion) and $(GitIgnoreTagVersion): determines whether the branch and tags (if any) will be used to find a base version. Defaults to empty value (no ignoring).

  $(GitNameRevOptions): options passed to git name-rev when finding a branch name for a commit (Detached head). The default is '&#45;&#45;refs=refs/heads/* &#45;&#45;no-undefined &#45;&#45;always'
                        meaning branch names only, falling back to commit hash. For the legacy behavior where $(GitBranch) for detached head can also be a tag name, use '&#45;&#45;refs=refs/*'.
                        Refs can be included and excluded, see git name-rev docs.

  $(GitSkipCache): whether to cache the Git information determined in a previous build in a GitInfo.cache for performance reasons. Defaults to empty value (no ignoring).

  $(GitCachePath): where to cache the determined Git information. Gives the chance to use a shared location for different projects. This can improve the overall build time.
                   Has to end with a path seperator Defaults to empty value ('$(IntermediateOutputPath)').

  $(GitTagRegex): regular expression used with git describe to filter the tags to consider for base version lookup. Defaults to * (all).

  $(GitBaseVersionRegex): regular expression used to match and validate valid base versions in branch, tag or file sources. By default, matches any string that *ends* in a valid SemVer2 string.
                          Defaults to 'v?(?<MAJOR>\d+)\.(?<MINOR>\d+)\.(?<PATCH>\d+)(?:\-(?<LABEL>[\dA-Za-z\-\.]+))?$|^(?<LABEL>[\dA-Za-z\-\.]+)\-v?(?<MAJOR>\d+)\.(?<MINOR>\d+)\.(?<PATCH>\d+)$'

  $(GitCommitDateFormat): value passed as the format option when trying to retrieve the git commit date. Defaults to %%cI (windows) or %cI (non windows).
