No way to specify script language in Document.update

[haynesgt]

elasticsearch_dsl==7.4.0

The script param is assumed to be a string here:

elasticsearch-dsl-py/elasticsearch_dsl/document.py

Line 391 in c089a40

if script:

but there is no way to set the language of the script.

It would be more intuitive if it set body["script"] = script if the script param were a dict.

That'd be a nice addition, would you be able to open a PR with the feature and test(s)?

@sethmlarson could you review the pr?
