Archive dbatools repo as tar.gz in CI workflow

The workflow now creates a tar.gz archive of the dbatools repository, including dot files and excluding .git, before uploading as an artifact. On download, the archive is extracted to restore the repo. This ensures all necessary files, including hidden ones, are preserved in the artifact.
