Upgrade nightly to 2025-09-26 for public-api compatibility

Updated from nightly-2025-01-21 to nightly-2025-09-26 to match the
requirements of public-api v0.50.2 used by cargo-rbmt.

The newer nightly generates rustdoc JSON in a format that's compatible
with recent versions of the public-api crate used for API checking.
