chore(lockfileless): Added rest of ManifestKinds (#301)

This PR introduces the rest of the manifest kinds we support to the
`ManifestKind` type's possible values.

- [x] I ran `make setup && make` to update the generated code after
editing a `.atd` file (TODO: have a CI check)
- [x] I made sure we're still backward compatible with old versions of
the CLI.
For example, the Semgrep backend need to still be able to *consume* data
generated
	  by Semgrep 1.17.0.
