Update mirror status command

We are in the process of moving the mirror status logic to release tools in gitlab-com/gl-infra/delivery#19333 (closed). We have already moved the logic to release tools in gitlab-org/release-tools!2472 (merged) and created a CI job to check the status and post it to slack in gitlab-org/release-tools!2479 (merged).

This MR updates the /chatops run mirror status command to trigger a pipeline on release-tools to fetch the mirror status rather than using the deprecated logic within chatops.

A separate MR will follow this one to remove all of the deprecated mirror status logic.

Local testing

I ran the command locally, which triggered a successful pipeline on release tools: https://ops.gitlab.net/gitlab-org/release/tools/-/pipelines/2089238. The mirror status was posted in #release_tools_tests:
