OCPBUGS-102222:[release-4.12] Go HTTP/2: Denial of Service via malformed SETTINGS_MAX_FRAME_SIZE frame

[Pranavgarud06]

Summary :

This PR bumps golang.org/x/net → v0.53.0 to remediate the HTTP/2 transport infinite-loop vulnerability (CVE-2026-33814 / GO-2026-4918).

Scope: this addresses the golang.org/x/net/http2 component only. The stdlib net/http half of the same CVE (fixed in Go 1.25.10 / 1.26.3) is remediated separately via the Go build toolchain and is out of scope for this PR.

Notes for Reviewers:

go mod edit -replace golang.org/x/net=github.com/openshift-sustaining/net@v0.35.0-sec.4
go mod tidy
go mod vendor
