Desktop client should not force user to setup a local core

[CheatCod]

@Ynng I think I heard you mentioning why this is necessary, is it possible to remove this restriction?

This issue occurs only on:

• Electron (macOS Monterey 12.3.1 and Windows 10 tested)

This exists to simplify the setup process.

We assumed that if someone downloads the desktop client, they want to run a lodestone core locally.
If they only want to control remote cores they can just use the web app.

We can remove this, just gotta

1. Add button to skip local core setup in Tauri
2. Add button in core selection screen to setup local core so it can be setup later
3. Track the skipped status so user won't be prompted again on restart of lodestone desktop

Is anyone planning on implementing this? I see it has been a little over a year and a half, and wanted to see if it would be easy to add.
