Cannot import local files on Linux

[nlholdem]

Setting the Source Storage asks me to set LOCAL_FILES_SERVING_ENABLED environment variable, but it is already set
A clear and concise description of what the bug is.

To Reproduce

1. Create new project
2. In Cloud Storage, set to local files.
3. Set absolute path
4. Click 'Add Storage''
5. See error:
   [ErrorDetail(string="Serving local files can be dangerous, so it's disabled by default. You can enable it with LOCAL_FILES_SERVING_ENABLED environment variable, please check docs: https://labelstud.io/guide/storage.html#Local-storage", code='invalid')]
   The documentation actually mentions a different env variable, LABEL_STUDIO_LOCAL_FILES_SERVING_ENABLED. In any case I set both of these in my shell before launching label-studio. I even put them in label-studio's own file at ~/.local/share/label-studio/.env. Still get the same error.

Environment (please complete the following information):

• OS: Ubuntu 22.04
• Label Studio Version 1.14.0.post0

My mistake, I hadn't exported the variable.
