Remove partially unsupported wizard CLI arguments

[Lms24]

According to our documentation (e.g.Readme), the wizard supports a few CLI args across the individual integration flows. This however is no longer true in the modern, clack-based wizard flows (Next, Sveltekit, Remix, ReactNative, Sourcemaps).

I would like to remove old baggage by dropping wizard options in a major release:

• --quiet IMO there's no need for a quiet flow, given that wizards are usually executed locally by users
• --signup The new login flow asks if users already have a Sentry account. Way more intuitive than specifying this via an option

We still have a bunch of older flows that theoretically support these options. Ideally, we find a way to continue support there. Maybe, yargs has an option for this.

This issue has gone three weeks without activity. In another week, I will close it.

But! If you comment or otherwise update it, I will reset the clock, and if you label it Status: Backlog or Status: In Progress, I will leave it alone ... forever!
