Processor - Ping people in revert MRs that didn't use the revert MR template
Context
In gitlab-org/gitlab!105290 (merged), we have introduced an MR template with important labels to set when a revert MR is being created, but it will not be used a lot until people know about it.
It's also important to use this template, because it would contain labels that would reduce friction in revert MRs (e.g. skip certain jobs to make the pipeline faster, skip changelog in case we are having a regression, ...).
Goal
Have a processor that would nudge users that made a revert MR without using the template (i.e. it doesn't have pipeline:expedite label set), and telling them about the template, with a link to the docs about the feature.
