fix: Organisation no longer required for Sentry CLI options

[bitsandfoxes]

Fixes #2058

This PR made the SDK respect Organisation tokens. Users using the the wizard going forward, won't have the Organisation set on the options as the org-slug will be taken from the embeddings of the token.

In case on non-organisation tokens (i.e. user tokens), the organisation can still be provided and will be used.

The relevant changes to tokens and sentry-cli are

• Simplified Upload Tokens for CI Usage rfcs#91
• feat: Use org and url from tokens sentry-cli#1673
