45.0.0 (2023-05-28)

Features

• add recommended-typescript-flavor configs (6042b77)
• for typescript configs, disable no-undefined-types; fixes #888 (ec41b90)

BREAKING CHANGES

• This should only impact users of typescript configs. TS should itself handle
  checking for undefined types, so the (imperfect) rule has been disabled for
  such users.
