Update closure externs

[zbynek]

It would be nice to have Closure externs updated to v20250723 or later to pick up improvements such as google/closure-compiler@bd2912e

I second this. I was expecting fixes for:

• google/closure-compiler@5aadfa7
• google/closure-compiler@b57e0aa

in release 1.3.0, but no luck as it's stuck on an old closure version.

Please update https://github.com/google/elemental2/blob/master/MODULE.bazel#L43 Thanks!
