Merge #7508

7508: Release 2.1.2 r=deivid-rodriguez a=deivid-rodriguez

### What was the end-user problem that led to this PR?

The problem was that I want to ship [a small regression fix](#7505), and also so tweaks to the development environment (#7506) that I want to use in the rubygems side to fix the CI errors in ruby/rubygems#3043.

### What is your fix for the problem, implemented in this PR?

My fix is to release 2.1.2
