Docs: Mark variable_width_histogram experimental (#58574)

We're tracking this aggregation's experimental-progress in #58573. We'd
like a little time to be able to make backwards incompatible changes to
the aggregation because we're not 100% sure about the request and
response format yet.

=== Variable Width Histogram Aggregation
experimental::["We're evaluating the request and response format for this new aggregation.",https://github.com/elastic/elasticsearch/issues/58573]
This is a multi-bucket aggregation similar to <<search-aggregations-bucket-histogram-aggregation>>.
However, the width of each bucket is not specified. Rather, a target number of buckets is provided and bucket intervals
are dynamically determined based on the document distribution. This is done using a simple one-pass document clustering algorithm
