Others here mentioned carykh's jumpcutter. I tried to get it to install but couldn't, then discovered it hasn't been updated in a long time.

There's even an issue with links to alternatives and forks: https://github.com/carykh/jumpcutter/issues/180

I tried out Auto-editor [1] and it works great for what I needed! Although for "removing" silence, I prefer to increase play speed instead of jump cutting.
