Support turning this

   uses: actions/checkout@v3

into

    # https://github.com/actions/checkout/releases/tag/v3
    uses: actions/checkout@2541b1294d2704b0964813337f33b291d3f8596b

Having a link to the source is convenient, to be able to read the release notes.

If the comment with the tag URL already exists, it would just update that sha corresponding to what the tag points to now.
