Docs: sync Jobs hardware flavors (add rtx-pro-6000, refresh example) (#2533)
- jobs-pricing.md: add the new rtx-pro-6000 (x1/x2/x4/x8) GPU flavors
(huggingface_hub v1.17.0, PR #4259).
- jobs-configuration.md: regenerate the `hf jobs hardware` example from
current output. The format changed since it was last pasted — lowercase
headers, a new `storage` (ephemeral disk) column, and a blank accelerator
cell for CPU flavors instead of "N/A" — and it now includes the
previously-missing cpu-xl, cpu-performance, h200, and rtx-pro-6000 rows.
All flavors verified against the unauthenticated GET /api/jobs/hardware, so
no employee-only hardware is exposed.
