Remove usage of transient settings to enable allocations in rolling upgrade docs (#29671)

Browse Source 
Since we disable allocation using persistent settings, we should be consistent and remove
the setting from the persistent storage. Otherwise an accidental restart will lead for shards
not being allocated.

Relates to #28757

NOTE: Because <<_precedence_of_settings, transient Once the node has joined the cluster, remove the `cluster.routing.allocation.enable`
settings take precedence over persistent settings>>, this overrides the setting to enable shard allocation and start using the node:
persistent setting used to disable shard allocation in the first step. If you
don't explicitly reenable shard allocation after a full cluster restart, the
persistent setting is used and shard allocation remains disabled.
Once the node has joined the cluster, reenable shard allocation to start using
the node:
