Use the --tags while unshallowing otherwise the tags are not found

Hi,

When we are using actions/checkout the check out happens by default with the --no-tags.
From this setup when we do an unshallow and then try to find the tags the tag is not found.
But when we use the unshallow using the additional --tags then it seems to work as expected.
git fetch --prune --unshallow --tags

Is this expected and does the fix sound reasonable?
