[FEATURE] Add overloads that takes multiple `QueryDescriptor`s to Filter()/Must()/MustNot()/Should() of `BoolQueryDescriptor`

[rlindber]

Is your feature request related to a problem? Please describe. The current code using Nest is generating QueryDescriptor object, that are finally combined in a BoolQueryDescriptor with calls to Filter(), Must(), MustNot() or Should(). Example signature from Nest client:

public BoolQueryDescriptor<T> Must(params QueryContainer[] queries)

Describe the solution you'd like The corresponding function for BoolQueryDescriptor in Elastic.Clients only takes one QueryDescriptor, instead of an array as in Nest. From Elastic.Clients:

public BoolQueryDescriptor<TDocument> Must(QueryDescriptor<TDocument> descriptor)

Could these four function be replaced with functions that take multiple QueryDescriptor objects, e.g. using "params", like this?

public BoolQueryDescriptor<TDocument> Must(params QueryDescriptor<TDocument>[] descriptors)

Describe alternatives you've considered It would require a lot of work to rewrite the existing code to used a function that take multiple object, like

public BoolQueryDescriptor<TDocument> Must(params Action<QueryDescriptor<TDocument>>[] configure)

or

public BoolQueryDescriptor<TDocument> Must(ICollection<Query>? must)

Thanks for raising this, @rlindber. I agree that this would be a good addition since there's no longer a relationship between Query (the equivalent of QueryContainer) and QueryDescriptor<T> (the equivalent of QueryContainerDescriptor) in the v8 client.

We should update the code-generator to handle this for any methods that already include an overload of params Action<QueryDescriptor<TDocument>>[] configure.
