Typed Client MSearch doesn't support include_named_queries_score

[etiennecl]

It is currently impossible to set the query parameter include_named_queries_score as part of the MSearch client. Although this is not documented, it is possible to add this query parameter, which will be applied to all searches. I believe the clients should allow setting this values as part of the typed client just like the other path values in this file

https://github.com/elastic/go-elasticsearch/blob/main/typedapi/core/msearch/msearch.go

// API name: include_named_queries_score
func (r *Msearch) IncludeNamedQueriesScore(includenamedqueriesscore bool) *Msearch {
	r.values.Set("typed_keys", strconv.FormatBool(includenamedqueriesscore))

	return r
}

It seems like a general issue in all clients du to the fact that the base definitions/documentation do not include this query parameter:
