pytask-latex paths are not set correctly

[janosg]

I had multiple bug reports from students that latex documents are not re-built after included figures or documents change. It seems that this comes from a wrong path in pyproject.toml that maybe was not updated after the paper folder was moved out of the src folder.

The current entry in pyproject.toml look like this:

[tool.pytask.ini_options]
paths = ["./src/project_name", "./src/paper"]

I think it should look like this:

[tool.pytask.ini_options]
paths = ["./src/project_name", "./paper"]
