Pin jupyterlab at >=4.4.0a2,<5.0.0 in projects/jupyter-collaboration package

[andrii-i]

Adds jupyterlab pin at >=4.4.0a2,<5.0.0 in projects/jupyter-collaboration subpackage. This would introduce a way to specify which versions of jupyterlab current version of jupyter-collaboration is compatible with which would prevent RTC-jupyterlab version mismatch issues for new versions of jupyter-collaboration.

• Fixes Should most collaboration python packages depend on jupyterlab? #425

Testing:

1. Create new conda environment
2. Install jupyterlab<4.4.0a2 by running pip install jupyterlab==4.2.0
3. Clone this PR and install it locally by running pip install -e . from projects/jupyter-collaboration
4. Run jupyter --version , note updated jupyterlab version

One open question about this PR being discussed in #425 (comment) is if platform_system!='Emscripten' should be added to the pin to account for wasm environments.

[andrii-i]

Based on discussion during the JupyterLab call today adding platform_system!='Emscripten' exception is not necessary for now as there are no known jupyter-collaboration wasm environments.
