CI: Run tutorials against other kornia versions

[johnnv1]

With the new CI setup (#81) we can choose against which kornia version runs the tutorials. By using the git reference to the env action.

Example

    uses: kornia/workflows/.github/workflows/[email protected]
    with:
      ref: 'main' # Or any git reference, tag, commit, etc -- so can be v0.7.0, etc

This ref input is the git reference of kornia/kornia repository.

The problem with it now, is that not all tutorials will work on older kornia versions, so this needs to be dealt with somehow
