MergeRequests::PushOptionsHandlerService has been updated to allow
adding and removing labels to a merge request using git push options.

To create a new merge request and add 2 labels to it:

      git push -u origin -o merge_request.create \
        -o merge_request.label="My label 1" \
        -o merge_request.label="My label 2"

To update an existing merge request and remove a label while
adding a different label:

      git push -u origin -o merge_request.label="My added label" \
        -o merge_request.unlabel="My removed label"

Refactor showStagedIcon property's behavior to match its name

Closes #66071

See merge request gitlab-org/gitlab-ce!32333

Previously the following syntax would fail in the linter with an
error 500:

```
include:
  template:
    - License-Management.gitlab-ci.yml
    - Dependency-Scanning.gitlab-ci.yml
    - SAST.gitlab-ci.yml
```

Now the error will call out specifically that the value
is not a string.
