feat(triggers): add Linear v2 triggers with automatic webhook registration (#3991)

* feat(triggers): add Linear v2 triggers with automatic webhook registration

* fix(triggers): preserve specific Linear API error messages in catch block

* fix(triggers): check response.ok before JSON parsing, replace as any with as unknown

* fix linear subscription params

* fix build
