arti: 2.4.0 -> 2.5.0

blog: https://blog.torproject.org/arti_2_5_0_released/
changelog: https://gitlab.torproject.org/tpo/core/arti/-/blob/arti-v2.5.0/CHANGELOG.md
diff: https://gitlab.torproject.org/tpo/core/arti/-/compare/arti-v2.4.0...arti-v2.5.0
trove: https://gitlab.torproject.org/tpo/core/team/-/wikis/NetworkTeam/TROVE

this release is non-breaking for users of the binary, but should provide
various transparent improvements (CGO, congestion control).
additionally, the upstream tag contains fixes for two medium severity
DoS issues: TROVE-2026-024 and TROVE-2026-027. we already had (and now
drop) the patch for the former, but this does fix the latter for us.

Fixes: TROVE-2026-027
