Outdated resource planning docs for Zeebe

[npepinpe]

Taken from a Slack comment (thanks Emma!)

I believe that https://docs.camunda.io/docs/next/self-managed/zeebe-deployment/operations/resource-planning/ might have some wrong information, such as idea that a max number of snapshots must be reached before deleting a log segment.
See - https://github.com/camunda/zeebe/blob/13e0e88082c5dec8b4d6134d560cbd9920e31fa4/ which shows that maxSnapshots was removed.
However the github doc edited by this also says the default logSegmentSize is 512MB but in the config files its 128MB.
Can someone confirm both the default log segment size and if there is a max snapshots or if a log can be deleted after all events are replicated, commited, processed, exported, and a snapshot exists.

Please update the default logSegmentSize (which is now 128MB) and remove references to max number of snapshots - there is always only one snapshot.
