Update package-lock.json and switch submodule to HTTP

[k8ieone]

In order to get Flatpak builds working, I've had to make a few changes.

1. Update package-lock.json
2. Switch the Typewriter submodule to HTTP

I've had to switch from SSH because Github doesn't allow pulling from SSH unless you add the machine's SSH key to a Github account. Since the builds will run on Flathub's CI servers, this is not feasible.

In case you need write access to the submodule from the main repo, I recommend using insteadOf in your git config.

Example:

[url "ssh://git@github.com"]
	insteadOf = https://github.com

Good stuff!

That other package will need to be resolved at some point somehow. It's not exactly important, but it's part of the monorepo and will come back next time the lock file gets updated.
