DOCS: Add Using MODEL parameters form lightwood into mindsdb docs.

Is your feature request related to a problem? Please describe.

It isn't clear from the current docs which models can be specified with the USING statement on this page.

This was raised by a customer.

The model section in the table tries to address this by linking to Lightwood here

However, this is confusing in a couple of ways:

1. The link is easy to miss.
2. MindsDB calls them "models" in USING parameter_key but you land on a page detailing "Mixers". A user would wonder are they the same?
3. The syntax/upper case/lower case is unclear from ones docs to the other (even if it is obvious why). Presumably it should be implemented as "LightGBM" in MindsDB not "mixer.LightGBM" for instance.
4. What is Lightwood? Should I be using it instead?

Describe the solution you'd like.

It would probably make sense to have a section somewhere in the docs of everything that MindsDB supports rather than rely on Lightwood docs.

Describe an alternate solution.
