Description

Currently, many issues lack information about the Manim Slides installation (correct venv, presence of one or multiple Manim bindings, Qt bindings) and I think a command that outputs this information would be of great help.

Additional information

It would make sense to export the Manim and ManimGL version (at least inside the package) and change the issue template to ask for manim-slides checkhealth's output instead of pip freeze.
