Bug#1077741: rust-gdk4-sys: autopkgtest regression with GTK 4.14

[Simon McVittie <smcv@debian.org>]

Source: rust-gdk4-sys
Version: 0.8.2-4
Severity: serious
Tags: trixie sid
Justification: https://release.debian.org/testing/rc_policy.txt §6a

Usertags: needs-update

rust-gdk4-sys is failing its autopkgtest with the recently-uploaded
GTK 4.14:

> 219s ---- cross_validate_constants_with_c stdout ----
> 219s Constant value mismatch for (gint) GDK_MEMORY_N_FORMATS
> 219s Rust: "28"
> 219s C:    "33"

It presumably needs to be updated in unstable. The version in experimental
is probably suitable, and might just need a re-upload to unstable?

Thanks,
