[ML] Add docs for ML info endpoint (#35783)
This endpoint was not previously documented as it was not
particularly useful to end users.  However, since the HLRC
will support the endpoint we need some documentation to
link to.

The purpose of the endpoint is to provide defaults and
limits used by ML.  These are needed to fully understand
configurations that have missing values because the missing
value means the default should be used.

=== Get Machine Learning Info API

<titleabbrev>Get Machine Learning Info</titleabbrev>
++++
Returns defaults and limits used by machine learning.
==== Request
`GET _xpack/ml/info`
==== Description
This endpoint is designed to be used by a user interface that needs to fully
understand machine learning configurations where some options are not specified,
meaning that the defaults should be used. This endpoint may be used to find out
what those defaults are.
==== Authorization
You must have `monitor_ml`, `monitor`, `manage_ml`, or `manage` cluster
privileges to use this API. The `machine_learning_admin` and `machine_learning_user`
roles provide these privileges. For more information, see
{stack-ov}/security-privileges.html[Security Privileges] and
{stack-ov}/built-in-roles.html[Built-in Roles].
==== Examples
The endpoint takes no arguments:
[source,js]
