ci: declare .hypatia-ignore for 6 vendored ReScript unicode test fixtures

The package-anti-pattern gate flagged 6 .res files under
rescript-ecosystem/.../unicode/src/<emoji>/ — vendored upstream
rescript-compiler test fixtures (not project source, not migration
candidates). Add a top-level .hypatia-ignore to declare them as
exemptions so the gate can pass on this docs-only PR.

Unblock condition: removal happens only if rescript-ecosystem/ is
itself dropped from the vendor tree.
