Temporarily pin Faraday related gems

What does this MR do?

Temporarily pin Faraday related gems
    
- Faraday 2.9.0 introduced a dependency on net-http 0.3.0 which causes
  conflicts with the version of net-http specified in the Omnibus and
  GitLab Rails project Gemfiles. The version of net-http cannot be
  updated until DNS rebinding fixes are complete in the GitLab rails
  project, so this pins the Faraday gem versions as a stopgap until the
  real fix is ready, validated, and merged.
