docs: update tinybird CLI installation and auth steps

[devnucleus950]

This PR updates the Tinybird CLI installation and authentication steps to use the modern flow, as the old interactive method via pip/pipx is deprecated.

Fixes dubinc/dub#3727

Summary by CodeRabbit

• Documentation
  • Simplified CLI setup: installation now uses a single installer command for easier local setup.
  • Streamlined authentication: replaced the interactive token paste flow with a one-step login command to simplify sign-in.

168-175: Align Tinybird setup wording across docs

This section now uses the new flow, but docs/self-hosting.mdx:103-117 still references a different installation path. Consider updating both docs to the same Tinybird setup flow to avoid conflicting instructions.

instructions are inconsistent across docs: update the "Install the Tinybird CLI"
section (the paragraph that shows `curl https://tinybird.co | sh` and `tb
login`) to match the new flow used in local-development, and edit the older
self-hosting Tinybird section to use the identical wording and steps (same
install command, authentication via `tb login` and admin token) so both docs
present the same setup flow.

reads "bash Terminal" (keep the command itself unchanged).

It wasn't necessary to paste a token. Just by running tb login, it was able to authenticate.

Hey, @pepeladeira
Thanks for the feedback! I’ve applied the suggested change.

@pepeladeira Thanks for the feedback! I’ve applied the suggested change.

@devnucleus950, also, I'm worried that the CLI command is only for MacOS and Linux. We should also mention the correct command for Windows users.

[devnucleus950]

I've added Windows-specific installation instructions as well.
