prefer-await-to-then should flag promise.catch/finally as well

[jp7837]

Description

For consistency, I feel that the prefer-await-to-then rule should also flag promise.catch and promise.finally so we can enforce async/await everywhere if desired.

Steps to Reproduce

1. Run prefer-await-to-then on code with a Promise.prototype.catch invocation

Expected behavior: catch call is flagged

Actual behavior: rule does not report a problem
