Latest version missing docutils dependency

[sswatson]

Description

1. Create a new Python project with its own virtual environment, pip install nicegui, and then try to import nicegui.
2. I expect the import statement to work with no errors.
3. I get the error No module named 'docutils'. If I then pip install docutils, then everything works fine.

This leads me to believe that there's a missing dependency declaration.

This is for the version released on February 26, 2024.

Thanks for pointing this out, @sswatson!
@rodja Has already created a PR this morning to fix this issue. I think I'll quickly create a bugfix release.
