add ci_id_token_sub_claim_components to editProjectOptions

[duncan485]

This adds the ci_id_token_sub_claim_components to the gitlab project.

Note that it is currently only possible to edit this setting, so I did not add in the createProjectOptions (awaiting API implementation from gitlab: https://gitlab.com/gitlab-org/gitlab/-/issues/477260 ).

This seems a little risky -

1. The field isn't documented as part of the official API
2. The example posted isn't a GitLab employee (to my knowledge), so it's not necessarily a "sanctioned" workaround
3. There's explicitly a story open to add separate API support.

It feels like we should wait until there is an official API support; the stance on this library is to not support "non-public" APIs unless there's a very compelling reason to do so.

Any thoughts here @timofurrer ?

Hi @RicePatrick I get what you are saying. And can't say I disagree, shall I convert this one to WIP, and revisit once the api implementation on the giltab side has been done?

@duncan485 - given we'll be migrating this project to gitlab.com (hopefully) tomorrow, I'd say let's close it and we can revisit it there once the gitlab side is done, yeah :)
