[jb] check maxHeapSize of IDE server and guide users to set vmoptions in .gitpod.yml
- Register a background activity (GitpodStartupActivity) for handling postStart events - Add YAML plugin dependency for parsing & navigating PSI elements (AST) in .gitpod.yml - Show warning notification when the runtime Xmx is different from the configured Xmx - Add edit/create-if-missing .gitpod.yml quick actions, and navigate caret to `vmoptions` YAML key if exists - Add help action for browsing gitpod.yml references - Set -Xmx for the `runIde` task (only affect local sandbox IDE instance with the developed plugin), which can be modified for local testing purpose
