Fix validator for std-with-versions

For projects that has branch type 'std-with-versions' (like ironic,
because they cut bugfix/<MAJOR>.<MINOR> bugfix branches) the new stable
branch name style (like stable/2023.1) does not pass validator. This
patch extends the validator to accept these branch names, too.
