Use regex allowlist so pinned vendor and master both build

The previous `allowlist_type("rbs_ast_ruby_annotations_t")` relied on
bindgen's transitive allowlisting through the union. That works against
the current master (where the union lists all 14 annotation members
after auto-generation), but CI vendors the pinned v4.0.2 tag via
`rake rust:rbs:sync`, whose union only has 6 members. The other 7
annotation structs referenced by ruby-rbs therefore never appeared in
bindings.rs, breaking `cargo test`.

Switch to the regex `rbs_ast_ruby_annotations_.*` which matches every
annotation struct directly (and still includes the union itself) in
both the pinned vendor and the current master, preserving the
auto-follow property intended by this PR.
