Module documentation renders in a weird way

[arnaudsjs]

Example: https://docs.inmanta.com/inmanta-service-orchestrator-dev/8/reference/modules/aci.html#aci.resources.StandaloneProvider

• The handler name is rendered as ````. This happens because the handler doesn't set a name, because there is only one handler for multiple resources.
• The same handler class is displayed multiple times in the documentation.

discussed in planning meeting:

1. for the ```` issue, double check whether the name is not set + check with solutions team if we should allow it to be absent (it's currently typed str, not `Optional[str]`).
2. The same handler class is displayed multiple times because we reuse the same class for multiple resources (stacked @provider). This should be displayed correctly. Investigate what is easiest.
3. The generated documentation may be meaningless in the first place, given that we will soon be able to use the README.md to drive the docs. Check with the solutions team how relevant this ticket is (if we wouldn't ever generate it for these modules, it's not that meaningful).

Assigning to @hlloreda to check on point 3.

Point 1 seems to have disappeared. But point 2 is still relevant when it comes to generic handlers, so we should take action on this (this part of the documentation is still used).
