Update documentation (#893)

### Summary
* Renames docs page to "Monarch KG Tools"
* Moves `release-process.md` from
https://github.com/monarch-initiative/monarch-documentation/blob/main/src/docs/release-process.md
into these docs
* Updates CLI documentation after changes made in 64b4d01
* Folds the existing "Welcome", "Usage", and "Response Data Model"
sections into one broader section for "monarch-py"
* Removes the "API Reference" section, as it is redundant with
information already contained in "Usage"

### Related issues
