feat: add WithMergeStatusRecheck property

[theknut]

Add missing property WithMergeStatusRecheck to MergeRequestQuery.

From GitLab documentation

Listing merge requests might not proactively update merge_status (which also affects the has_conflicts), as this can be an expensive operation. If you need the value of these fields from this endpoint, set the with_merge_status_recheck parameter to true in the query.
