docs: mention GC atime update check for tuning options

Browse Source 
Document the gc-atime-safety-check flag and describe the behavior it

datastore tuning options.

sync level, to make it clear that still belongs to the previous

* ``gc-atime-safety-check``: Datastore GC atime update safety check:
You can explicitly `enable` or `disable` the atime update safety check
performed on datastore creation and garbage collection. This checks if atime
updates are handled as expected by garbage collection and therefore avoids the
risk of data loss by unexpected filesystem behavior. It is recommended to set
this to enabled, which is also the default value.
If you want to set multiple tuning options simultaneously, you can separate them
with a comma, like this:
