Build broken since removal of TrustAuthority from Solmate

[gakonst]

Problem

Every since https://github.com/Rari-Capital/solmate/issues/66, TrustAuthority is no longer present, which means that the build / tests now fail.

Repro

dapp build:

ParserError: Source "lib/solmate/src/auth/authorities/TrustAuthority.sol" not found: File not found.
 --> src/test/VaultInitializationModule.t.sol:7:1:
  |
7 | import {TrustAuthority} from "solmate/auth/authorities/TrustAuthority.sol";
  | ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

this shouldnt be a problem unless you're force updating its deps when u build— it depends on a pre v6 commit
