This is more concise and ruby does a better job performance-wise.

This used to be `bsearch_index` already but https://github.com/ruby/prism/commit/6d8358c08395438d5924777c1fc3001a5ebf0aa3 changed it.

> Yeah the edge case was that the value matched an element exactly

Gets called as part of pretty-printing nodes.
Further reduces the time for `SnapshotsTest` by ~16% for me.

While the latter creates an intermediate array of all method names
including all ancestors, the former just traverse the inheritance
chain and can stop if found once.
