Module DOCUMENTATION should match argspec (#34895)

* Module DOCUMENTATION should match argspec

Large update of many modules so that DOCUMENTATION option name and
aliases match those defined in the argspec.

Issues identified by https://github.com/ansible/ansible/pull/34809

In addition to many typos and missing aliases, the following notable
changes were made:

* Create `module_docs_fragments/url.py` for `url_argument_spec`
* `dellos*_command` shouldn't have ever had `waitfor` (was incorrectly copied)
* `ce_aaa_server_host.py` `s/raduis_server_type/radius_server_type/g`
* `Junos_lldp` enable should be part of `state`.
