feat: Add support for Trunk (#4293)

* Add trunk-lsp client to lsp-mode

Trunk is a meta-linter designed to offer a single interface for managing
and running over 100 linters and formatters. This lsp-mode client
attempts to provide a similar experience to the official Trunk VSCode
extension. See https://docs.trunk.io/check for more info.
