[DOCS] Relocate `indices` module content (#54903) (#57413) Moves `indices` content from the [Modules][0] section to the [Configuring Elasticsearch][1] section. Also removes the [Indices][2] landing page and adds a related redirect.

The indexing buffer is used to store newly indexed documents. When it fills
up, the documents in the buffer are written to a segment on disk. It is divided
between all shards on the node.
The following settings are _static_ and must be configured on every data node
in the cluster:
`indices.memory.index_buffer_size`::
Accepts either a percentage or a byte size value. It defaults to `10%`,
meaning that `10%` of the total heap allocated to a node will be used as the

`indices.memory.min_index_buffer_size`::
If the `index_buffer_size` is specified as a percentage, then this
setting can be used to specify an absolute minimum. Defaults to `48mb`.
`indices.memory.max_index_buffer_size`::
If the `index_buffer_size` is specified as a percentage, then this
setting can be used to specify an absolute maximum. Defaults to unbounded.
