Subject: [PATCH] Fix/enospc (#2789)

* fix: Handle ENOSPC error from chokidar

Now listens to the error event to check if "ENOSPC" occurrs.
The watcher will then automaticly restart in polling mode, so that
the user still sees his reqeusts / collections.

Fixes: https://github.com/usebruno/bruno/issues/1877

* Add more code comments, add !forcePolling to prevent endless loops and update error message

* fix: Also listen for EMFILE for too many watched files
