[release-4.22] OCPBUGS-101997: Bump golang.org/x/net to v0.53.0

[mariocr73]

What this PR does / why we need it:
Bumps golang.org/x/net from v0.48.0 to v0.53.0 to fix CVE-2026-33814 (GO-2026-4918), an infinite loop in the HTTP/2 transport triggered by a malformed SETTINGS_MAX_FRAME_SIZE frame. Reachable via keystone.NewKeystoneAuth -> http2.Transport. Verified with govulncheck before/after (no longer reported) and go build/go vet ./... clean across the whole repo.

Jira: OCPBUGS-101997

Special notes for reviewers:
go.mod's go directive stays at 1.25.5 (no toolchain bump). The vendor diff also includes mandatory transitive bumps (x/crypto, x/sys, x/term, x/text, and via x/text: x/tools/x/sync/x/mod) — required by x/net@v0.53.0's own
go.mod, not optional/unrelated churn.
