What does this MR do and why?

Update rails to version 7.0.8.6

It fixes several CVEs related to regular expression denial of service vulnerabilities. We were not affected by them thanks to the mitigations in Ruby 3.2 but this upgrade will prevent the CVEs from showing up in vulnerability scanning results.

Vulnerabilities

Changelogs

  • 7.0.8.5 Addresses the CVEs
  • 7.0.8.6 "These address a single bug in last week’s security releases in the block_format helper."

I followed the upgrade process https://docs.gitlab.com/ee/development/rails_update.html. There are no new @rails/ujs and @rails/actioncable version for this update. Gemfile.next was already at a version where those CVEs are patched.
