feat: support querying by ID

What does this MR do and why?

feat: support querying by ID

Add support for querying by ID in issues, MRs and work items. Also add support for querying MRs by a list of reviewers and approvers.

How to set up and validate locally

Now you can do: id = 123 or id in (1, 2, 3) for issues and MRs.

To query MRs, you can do type = MergeRequest and id in (1, 2, 3). Similarly for work items, you can do type = Objective and id in (1, 2, 3).
