Core Rule Set: a repository's name passes in the adopt form's id (closes #365)

While bodies are read, the forms that adopt or delete an unadopted
repository were refused when the repository's name held a command, a
system file's name or a shell path, such as alice/python3-app,
alice/.profile or robin/assets. id there now skips 930120, 932120, 932160
and 932260. The paths are gitea's /-/admin/repos/unadopted, Forgejo's
/admin/repos/unadopted, and /user/settings/repos/unadopted, which both
serve.
