monitor-components: stop looking for mimalloc updates (#6334)

As of #6231, Git for Windows
does not use mimalloc anymore (because the system allocator has sprouted
comparable performance in the meantime).

So let's not bother looking for new versions of that project, no
reaction is needed from Git for Windows' side anymore when those appear.
