Removes `testenv` annotations and related code. These annotations originally let you skip x-pack snippet tests in the docs. However, that's no longer possible.

When running a rate aggregation without setting the field parameter, the result is computed based on the bucket doc_count.
This PR adds support for a custom _doc_count field.
Closes#77734
rate aggregation should support being a sub-aggregation
of a composite agg.
The catch is that the composite aggregation source
must be a date histogram. Other sources can be present
but their must be exactly one date histogram source
otherwise the rate aggregation does not know which
interval to compare its unit rate to.

This replaces the `script` docs for bucket aggregations with runtime
fields. We expect runtime fields to be nicer to work with because you
can also fetch them or filter on them. We expect them to be faster
because their don't need this sort of `instanceof` tree:

In some cases when the rate aggregation is not a child of a date histogram
aggregation, it is not possible to determine the actual size of the date
histogram bucket. In this case the rate aggregation now throws an exception.
Closes#63703
