….org/x/crypto/ssh: Denial of Service via crafted AES-GCM packet decoder inputs

[openshift-4.22]

fix(deps): bump golang.org/x/crypto to v0.52.0 for CVE-2026-46597

Upgrades golang.org/x/crypto from v0.48.0 to v0.52.0 to remediate
CVE-2026-46597 (GHSA-q4h4-gmj2-qvw2, CVSS 7.5 High), an integer
underflow in the AES-GCM packet decoder in golang.org/x/crypto/ssh
that allows a remote unauthenticated attacker to crash the process
via a crafted SSH packet.

The affected symbol ssh.Dial is directly called in
cmd/infra/aws/proxyca.go via the hypershift create infra aws
CLI command. Operator binaries are not affected.

This also remediates 4 additional x/crypto/ssh vulnerabilities
fixed in v0.52.0: GO-2026-5020, GO-2026-5019, GO-2026-5018,
GO-2026-5017.

Transitive golang.org/x/* dependencies (net, sys, sync, mod, term,
text, tools) were updated to maintain compatibility.

Verification:

• make build: all 6 binaries built successfully (hypershift-operator, control-plane-operator, control-plane-pki-operator, karpenter-operator, hypershift, hcp)
• make test: all 191 test packages passed, 0 failures
