fix(ci): quote compliance-pr.yml name to fix invalid YAML (#1003)

The unquoted colon in `name: compliance: review (advisory)` (introduced
by #890's em-dash removal, which swapped an em dash for a colon
in-place) makes YAML read it as a nested mapping key, so GitHub can't
parse the workflow at all - every run of it fails with 0 jobs scheduled,
on every branch and PR repo-wide.
