[andreahlert]

Introduces a new apache-airflow-providers-stripe provider for Apache Airflow, discussed on the dev mailing list at https://lists.apache.org/thread/r9fr6571w3ssx07bnd5lgc9m88r1xy3c

What's included:

• StripeHook backed by the official stripe-python SDK (>=7.0.0)
• Automatic pagination via auto_paging_iter() — no memory blow-up on large result sets
• list_all() and retrieve() convenience methods
• stripe connection type with UI field behaviour (API key in the Password field)
• Optional Stripe API version pinning via connection Extra field
• 12 unit tests covering caching, pagination, error paths, and the four main resources (Customer, Subscription, Invoice, Event)
• RST documentation and connection guide
• lifecycle: incubation per AIP-95

The failing checks are unrelated to this PR:

• airflow-ctl:P3.11/P3.13 and Test git clone on Windows: transient GitHub Actions infrastructure error (fatal: could not read Username for 'https://github.com': terminal prompts disabled) — runner failed to checkout the fork. Same error seen on other PRs today.

• Breeze unit tests: failing on test_validate_provider_info_with_schema for the OpenAI provider ('ai-inference' is not of type 'object'), pre-existing on main. Also visible on Improve auto-triage: fake-SUCCESS detection, check status display, and triage tracking #63389.

All provider-specific checks pass. Locally verified: 12/12 unit tests pass, prek run --from-ref main --stage pre-commit clean.

@potiuk I assume this is because of ongoing discussions on devlist?
