Merge #147122

147122: ci: deadmansnitch for code-cover-gen GH action r=darrylwong,herkolategan a=srosenberg

Previously, we had added active monitoring for
`code-cover-publish` [1]. However, this time
`code-cover-gen` kept failing during build [2].
The latter workflow has `continue-on-error` in
order to report the (failure) status to Reviewable.io. Effectively, it was silently failing.

This change adds active monitoring for `code-cover-gen`. 
DMS will alert testeng in case any of the workflow steps fail repeatedly 
during the 24h interval.
