[Feature request] Able to ignore bots for posting comments/tagging issues

[Belphemur]

Hello,

In most of my repository, I have dependabot enabled (with auto-merge after test passes), a lot of the lib get updated quite a lot and I end up with a lot PR relating to dependencies update.

When it's time to do a release, semantic-release/github will go and post a comments on all those PR... This spam me aquite a lot. I love the feature of posting comments (especially for human made PR or Issue), but can we disable it for bots ?

Having a blacklist of users would be great !
