feat(`forge doc`): support `repository` field to link to a directory in a directory structure rather than a URL

[PaulRBerg]

Component

Forge

Describe the feature you would like

The forge doc settings allow for a repository field but they do not allow a directory path:

https://getfoundry.sh/config/reference/doc-generator#documentation-generator

A feature like this is essential for monorepos.

For example, an app might be stored at packages/foo (instead of the root directory).

Additional context

Hi! I’d love to work on this issue as my first contribution to Foundry.

I understand the goal is to support a new repository-path field in the [doc] section of foundry.toml, so that forge doc can correctly generate GitHub links for monorepos with subdirectories.

If this is still available, I’d be happy to take it up. Would appreciate any guidance or tips to get started!
