Update version tag comments from v6 to v6.0.1 for actions/checkout (#14)

Updated inline version comments for `actions/checkout` to reference the
specific patch version `v6.0.1` instead of the major version tag `v6`.

**Changes:**
- `.github/workflows/Auto-Release.yml` - Updated comment from `# v6` to
`# v6.0.1`
- `.github/workflows/Linter.yml` - Updated comment from `# v6` to `#
v6.0.1`
- `.github/workflows/Action-Test.yml` - Updated comment from `# v6` to
`# v6.0.1`

The commit hash `8e8c483db84b4bee98b60c0593521ed34d9990e8` remains
unchanged and correctly points to version 6.0.1.
