Tag dockerfile/1.5.0-labs-rc1 is not valid for labs version

[giggsoff]

I can see that dockerfile/1.5.0-labs-rc1 is not labs version because release script expects suffix to be labs. So the tag should be in form dockerfile/1.5.0-rc1-labs to be labs version.
Should we adjust release script to handle both cases?

Yes looks like we have done the same with https://github.com/moby/buildkit/releases/tag/dockerfile%2F1.4.0-labs-rc1 and https://github.com/moby/buildkit/releases/tag/dockerfile%2F1.4.0-labs-rc2.

#3204 would avoid this in the future hopefully, see #3204 (comment).

@crazy-max sorry for pinging you, but seems the same problem come with the new release: https://github.com/moby/buildkit/releases/tag/dockerfile%2F1.5.0-labs-rc2
