Work items GraphQL API - additional query filters

Release notes

You can now filter your work items more effectively with our GraphQL API, which now includes additional query filters for dates(created, updated, closed, due), health status, and weight. This improvement gives you greater flexibility in managing your projects, allowing you to quickly find and organize your work items based on various criteria, streamlining your workflow and boosting productivity.

Summary

Currently, the work items API lacks the feature to query by dates (created, updated, closed, due), health status, progress (for OKRs) and weight. To maintain parity with existing GLQL features, we should add that feature to the GraphQL API.

This work is blocking Knowledge's ability to migrate GLQL to use the work items GraphQL API as noted in gitlab-org/gitlab-query-language/glql-rust#46
