Update Conway example

[quaquel]

This adds a solara-based app.py, renames the old app.py to st_app.py for streamlit, updates readme.md with correct run instructions, and some minor cleanup and removal of oudated files.

Thanks! Could you maybe add screenshots how it looked before and after?

[quaquel]

There is no before because there was no solara version.

Sliders to change the grid size and initial fraction alive would be nice. You can steal them from: mesa-examples/examples/conways_game_of_life_fast/app.py

Disabling the gridlines and making the agents square would be really improve the viz, see how it looks with the PropertyLayer visualisation. But that can be another PR.

Otherwise, looking good, so going to pre-approve. A screenshot of the final viz in the PR description would be appreciated.

I agree, but changing the marker requires changes in matplotlib.py. Enabling/disabling gridlines is something that probably should become controllabe at the level of make_space_matplotlib.
