(DOCSP-12329) updates OM profiler page info (#118)

This PR moves over ongoing changes from [this
PR](10gen/mms-docs#5010) from the old mms repo.

Addressing outstanding feedback from @Isabel11 from the old PR:

> Have you verified that

> Change Slow Operations Threshold
> Request Index Suggestions
> do work in OM? I am not sure these are supported features in the
Profiler page (I may be wrong here)
> 

**Request Index Suggestions** did not appear to be a supported feature
in the Profiler page, so I removed the corresponding section.

> Profiler is its own tab on the page - metrics displays metrics
specifically but is separate from Profiler.

Addressed in this new PR.

Referencing the sentence "Log data is processed in batches. Data can be
delayed up to five minutes from realtime.":

> I am curious where the 5 minutes is coming from? Is this the mongod
batching the logs?

This information was derived from [the corresponding
page](https://www.mongodb.com/docs/atlas/tutorial/profile-database/) in
the Atlas docs. [See
