fix: build typescript in prepublish scripts

This fixes the problem that the cli gets built before semantic-releaser updates the version. Because of this the released `0.1.0` shows `0.0.1` when running `nodecg-io --version` because it was built with that version which copies the `package.json` into the `build` directory. Then semantic-release updates the version and the copied `package.json` isn't updated.

With this change we don't build the cli in a ci step anymore, but with the npm `prepublish` hook. That way semantic-release will bump the version and run `npm publish` which will then build the cli with the update version.
