Ignoring dir doesn't work when checking diagnostics

How are you using the lua-language-server?

NeoVim

Which OS are you using?

MacOS

What is the issue affecting?

Diagnostics/Syntax Checking

Expected Behaviour

When I set workspace.ignoreDir in .luarc.json it should exclude these folders from check when calling:

lua-language-server --check="some/path" --configpath="some/path/.luarc.json"

Actual Behaviour

The tool still prints errors in 3rd party dir.

Reproduction steps

1. Create .luarc.json and put:

{
  "workspace.library": ["${3rd}/luassert/library"],
  "workspace.ignoreDir": ["${3rd}/luassert/library"],
  "diagnostics.globals": ["vim", "require", "describe", "it", "P"],
  "diagnostics.disable": ["different-requires"]
}

2. Run:

lua-language-server --check="${DIR_SRC}" --configpath="${PWD}/.luarc.json" --checklevel=Information --logpath="${DIR_OUT}" --loglevel=error

Additional Notes

No response

Log File

No response

Reproduce the issue with the supplied .luarc.json and the lua-language-server --check command, then trace how workspace.ignoreDir is applied during diagnostics checking. Done means files under the configured ignored directory produce no diagnostics while checking the requested path.
