Remove special logic for oops

https://github.com/JCSDA-internal/jedi-ci/pull/21 added this section in `ci_action/main.py`.

OOPS configs must be updated (including itself in unit test deps) and this can be reverted.

```py
    # TODO: Remove this special logic for oops once oops updated config is rolled out.
    if target_project_name == 'oops':
        unittest_deps = ['oops']
```
