[docs] Add param notes to DSL search.delete documentation, fix broken links (#2861) (#2869)

* Add param notes to DSL search.delete documentation, fix broken links

The preferred way of passing parameters to the DSL `Search.delete` appears to be calling `Search.params` first,
but this is only ever discussed in GitHub issues like
elastic/elasticsearch-dsl-py#1115
and elastic/elasticsearch-dsl-py#1395.

To help anyone else who has stumbled across this, I added a note about this to the documentation.

I also went ahead and updated the links for the `Search.scan` and `FacetedSearch.params`
methods to the most recent versions since they were 404ing.

* make sync and async changes the same

+To pass [deletion parameters](https://elasticsearch-py.readthedocs.io/en/latest/api/elasticsearch.html#elasticsearch.Elasticsearch.delete_by_query)
+in your query, you can add them by calling ``params`` on the ``Search`` object before ``delete`` like this:
+
+```python
+s = Search(index='i').query("match", title="python")
+s = s.params(ignore_unavailable=False, wait_for_completion=True)
+response = s.delete()
+```
