If a Library has a variable in the path, arguments are not found

[Akselmo]

Describe the bug If a Library has a variable in the path, arguments are not found I have replicated the issue in the included zip file, but here's the gist of it:

BrokenExample.robot

*** Settings *** 
Library        ${ROOT}/libs/Example.py    ${EXAMPLE}

.vscode/settings.json

{
    "robot.variables": {"ROOT":"${workspaceFolder}", "EXAMPLE":"hello"},
    "robot.libraries.libdoc.needsArgs": ["../libs/Example.py"]
}

I've tried various different ways to use the needsArgs here: ["../libs/Example.py", "Example", "${ROOT}/libs/Example.py"]

None of them seem to fix the issue.

The library is unresolved and i get the following error

Unresolved library: ${ROOT}/libs/Example.py.
Error generating libspec:
Library 'Example' expected 1 argument, got 0.
Consider using default arguments in the ${ROOT}/libs/Example.py constructor and
calling the "Robot Framework: Clear caches and restart" action or
adding "${ROOT}/libs/Example.py" to the "robot.libraries.libdoc.needsArgs"
setting to pass the typed arguments when generating the libspec.

To Reproduce Steps to reproduce the behavior:

1. Download the included zip
2. Open it in VSCode
3. Try various different parameters and the problem persists: The LS can't find the Example.py file and/or the parameter.

Expected behavior The LS would resolve the Library and it's path as normal, like when using ../libs/Example.py

Versions:

• OS: Windows 10, Debian 11, Fedora 37 KDE
• Robot Framework Version: 6.0.2
• Robot Framework Language Server Version: 1.9.0
• Client Version: VSCode 1.76

From what I've gathered, it seems the ROOT variable is not resolved during the time when the docs are generated, so it doesn't match anything in the robot.libraries.libdoc.needsArgs
