Abstract contracts not rendered

[SebastienGllmt]

If you have an abstract contract in your project, there is no documentation generated for any of it other than the top-level comment block for the contract (ex the title)

The readme of this project does say that

Due to the technical limitations of the Solidity compiler, the documentation of private and internal functions is not rendered. Hence, the documentation of libraries might be close to empty!

I'm not sure if abstract contracts fall under this scope as well, but abstract contract docgen does work in https://github.com/OpenZeppelin/solidity-docgen at least
