Documentation available only in raw RST format

Problem

There is documentation inside https://github.com/crate/crate-operator/tree/master/docs. However, documentation is in the RST format, meaning it doesn't render in a human-friendly format.

The main README links for example to https://github.com/crate/crate-operator/blob/master/docs/source/configuration.rst for reading up on parameters, but its the raw RST, which doesn't render properly.

There does not seem to be a hosted version of the documentation on cratedb.com/docs. There is a deployment to GitHub pages (https://crate.github.io/crate-operator/), but clicking on links there leads back to the raw RST files.

Suggestion

Similar to cratedb-toolkit, there could be a hosted version of the documentation on readthedocs.io (https://cratedb-toolkit.readthedocs.io/). Ideally, it would also be available on cratedb.com/docs.
