chore: remove retired bedrocks

[SteelWagstaff]

We've retired two bedrocks, so we can remove them from the autoupdater.

I'm curious to know what sort of impact this will have on our github action usage too.

Definitely it will reduce the minutes consumption because is not gonna trigger composer update in those bedrocks anymore 🤖 ✨ @cmurtagh
