[RUN AS-IF-FOSS] Fix regression in FOSS for search issue description highlight

Closes #254840

See merge request gitlab-org/gitlab!43068

Fix: GraphQL breaking change `assigneeUsername` changed to `[String!]`

See merge request gitlab-org/gitlab!43036

Add e2e tests for MR push options

See merge request gitlab-org/gitlab!42195

- Adds 5 spec files for different push options
- `Git::Repository` and `Repository::Push` can now handle push options
- Updates `Resource::MergeRequest` to merge via the API
- `Resource::Project` can now return merge requests
- Allow waiting for merges to appear in the activity feed (events API)

This fixes https://gitlab.com/gitlab-org/gitlab/-/issues/254840

The `#use_elasticsearch?` method is not defined in FOSS so we cannot
refer to it. As such the easiest way to handle this is to move the logic
into a helper and override in EE.
