Describe the bug

forge doc does not support overloaded functions in interfaces properly.
The doc generated for the interface is correct, but the doc for the contract uses the NatSpecs of the first function it finds with the same name in the interface.

Interface:

Contract:

I published an example repo here: https://github.com/KirienzoEth/foundry-forge-doc-overloaded-functions-interface-issue

I suspect it's because the name of the function is used instead of its signature when merging the comments:
