Command functions:serve - Can’t setup custom path for functions

Describe the bug

According to the documentation for route requests, it should be possible to set up custom route paths for my functions, so I can change the default paths as my needs.

Currently, the Config doesn't work at all, meaning that is like this option is not existent at all.

Steps to reproduce

1. Clone this repository: https://github.com/TulioPintoNeto/financial-control;
2. Run the command npm run functions or netlify functions:serve;
3. Hitting http://localhost:9999/api/hello return 404 (Functions not found...);
4. Alternatively, you can also use netlify functions:list to check the URLs and see that Config is not doing nothing at all.

Configuration

[functions]
directory = "src/api/routes"

Environment

System:

OS: Windows 10 10.0.19045
CPU: (4) x64 Intel(R) Core(TM) i7-7500U CPU @ 2.70GHz
Memory: 1.04 GB / 7.87 GB

Binaries:

Node: 18.18.2 - C:\Program Files\nodejs\node.EXE     
npm: 10.2.3 - C:\Program Files\nodejs\npm.CMD     

Start by reproducing the issue with netlify functions:serve and the provided [functions] directory configuration, then compare the behavior with netlify functions:list. Trace how these commands handle the configured function path and custom routes. Done means /api/hello resolves locally and the list command reports the configured URLs.
