Switch git override to stable BCR tag for nanobind_bazel

This comes following the first BCR release of nanobind_bazel.

Feature-wise, nothing substantial has changed, except that the extensions
are stripped of debug info when built in release mode, which reduces
clutter in the symbol tables.

No stubgen yet, since nanobind v2 has not been released yet.
