Add author filters on github integration

[felpsio]

Is your feature request related to a problem? Please describe. I have a channel on Slack that uses the github integration and we use it to keep track of PRs. But we also have vercel on our repo. Vercel automatically adds a comment on each PR saying that the PR is being deployed. This increases the number of messages in the channels and makes more difficulties to track what is happening.

Describe the solution you'd like I would like to add a filter where I can avoid notifications from specific authors. So I can add vercel[bot] to this blacklist and decrease the number of notifications in the channel..

Example: /github filter author vercel[bot]

Describe alternatives you've considered I didn't find other alternatives so far.

Additional context Where I would like to see this filter:
