extensions: document that `testedwith = 'internal'` is special
Extension authors (notably at companies using hg) have been
cargo-culting the `testedwith = 'internal'` bit from hg's own
extensions, which then defeats our "file bugs over here" logic in
dispatch. Let's be more aggressive about trying to give extension
authors a hint about what testedwith should say.
