Gitlab Component Upgrade

Hi Team,

We have upgraded the Gitlab from 13.1.11 to 13.8.8.
As per Gitlab 13.6.0 release Git version should be 2.29.0 or greater and Ruby should be 2.7.2.
If we upgrade gitlab from 13.1.11 to 13.8.8 these components are not upgrading along with Gitlab Upgrade.
Will anyone please suggest how upgrade these manually.
