Code Review

This pull request bumps the versions of the ostree and ostree-sys crates and introduces a new feature flag, v2025_3. My review has identified a couple of issues. Firstly, the new feature is missing its corresponding metadata for system-deps, which could lead to incorrect system library version checks. Secondly, the pull request title is inconsistent with the changes, as it mentions v2025_2 instead of the newly added v2025_3. I've provided comments with suggestions to address these points.

LGTM as is but marking draft since this needs to wait for a release of the C library.

@cgwalters can you merge and do the bindings crate release?

Hmm I'm trying to regenerate things locally and getting

target/tools/bin/gir -c conf/ostree-sys.toml
Error: "GirXml: conf/../gir-files/OSTree-1.0.gir at line 13:3: Unexpected element <format>"

Did you not hit this?
