fix(ci): netsim does not interact with PR comments on forks (#2777)

## Description

Seems like permissions are still messy and the netsim job fails on forks
whenever it interacts with a PR from a fork, even though it's on our own
repo and we allow it to run.

This simply drops any type of commenting on the PR from a fork.

Need to add back the required check for this job once it's merged.
