Update `httparty` to 0.22.0

Description

Updating the httparty gem unblocks the upgrade path towards Ruby 3.2.6. We have to bump this gem since we will upgrade two gems gitlab-dangerfiles and rake. The gitlab-dangerfiles pulls the gitlab@5 gem as a dependency, but because the gitlab gem depends on a newer version of the httparty gem, we need to update the httparty gem to get version 5.

Here is the dependency graph, I am also attaching the full version below:
