feat(workspace): expand forbidden subdomain validation (#9082)

Added new forbidden words and regex patterns to subdomain validation in
`update-workspace-input`. Enhanced the `ForbiddenWords` validator to
support both strings and regex matching. Updated tests to verify
regex-based forbidden subdomain validation.

Fix #9064
