Forge remappings support other directory structure

[KuTuGu]

Component

Forge

Describe the feature you would like

Currently forge remappings command only generate the mapping of dependencies under the lib folder.
Hope it can also support other folder path: src, test, script (also support custom name).
Otherwise, vscode does not support clicking to jump, can only be solved by manually adding remapping or relative path.

Additional context

Desired result:

src=src/
test=test/
script=script/
