The current shrink API snippet doesn't show you how to remove replicas or reduce primary shards.
Rather than duplicate those instructions from the shrink API docs, this removes the snippet. A link to the shrink API and shrink ILM action docs is already provided.
It also updates a delete index API snippet to avoid wildcards. Wildcard expansion for the delete index API is disabled by default in 8.0.
On the "Size your shards" page, the shard size recommendation assumes a time
series use case. Similarly, users shouldn't count nearly empty and rarely used
Enterprise Search system indices against the recommended shard count limit.
Closes#76328.
Changes:
* Revises the size your shards guide to use a 50GB shard guideline. This better aligns with our default in the ILM policy UI.
* Updates the language to indicate that the 50GB shard guideline is not a hard limit. Larger shards may work depending on the network and use case.
Reverts some changes added in #71367.
Revises the current 'How to avoid oversharding' docs to incorporate
information from our [shard sizing blog post][0].
Changes:
* Streamlines introduction
* Adds "Things to remember" section to describe how shards work
* Adds "Guidelines" section based on blog tips
* Creates a "Fix an oversharded cluster" section
