[feature] Always show content warning: use existing glitch feature (#1)

The modifications you made are somewhat janky; for instance, editing a toot with an existing content warning makes the UI look very weird and doesn't quite work.

Glitch already has a feature for this, so simply turn it on by default. This should do the same thing.
