ci(inference-providers): bump doc-builder pin to InferenceSnippet prerender fix (#2531)

* ci(inference-providers): bump doc-builder pin to InferenceSnippet prerender fix

The inference-providers doc build crashes when a provider/task section has no
snippet in the kit's `@huggingface/inference` (e.g. `together` +
`automatic-speech-recognition`, supported by the generator's 4.13.18 but not the
kit's pinned 4.13.15): the InferenceSnippet component dereferences
`clients.length` on undefined → SvelteKit 500 → build fails on main and every PR.

Bump the pinned doc-builder ref for both build workflows to the fix
(huggingface/doc-builder#791), which defaults `clients` to `[]` so the prerender
no longer crashes on an unsupported combo.

* ci: repoint doc-builder pin to merged main (huggingface/doc-builder#791)

#791 merged; point both build workflows at the resulting doc-builder main
commit (bcff59f) instead of the fix-branch head.

* ci: bump upload workflow doc-builder pin to bcff59f for consistency

Keep all three inference-providers workflows on the same doc-builder main commit.
