Mergebot live on community index

[mosteo]

A new automation is running on the community index that will merge crate releases that pass the automated checks after one hour of being marked ready for review. It runs hourly so there will be some skew.

This bot targets only "simple" PRs: releases for existing crates that have minimal changes in metadata w.r.t. to the previous release.

Excluded from automerge are externals, first releases, and any significant (read the docs) changes to metadata.

The bot can also process yanked releases (those modified just to add available=false), which is the Alire way to withdraw a release (deletions are in general not allowed).

We will be closely monitoring this automation for a while. Please report any suspicious activity.
