Release manifest URLs are still pointing to GCS buckets instead of OCI buckets

[adityavshinde]

Problem

Currently, the tektoncd/cli repository still contains outdated references to storage.googleapis.com in its documentation, installation guides, and scripts.

Proposed Solution

We need to find and replace all instances of the old GCS URLs with the new infrastructure URLs throughout the repository.

Specifically, we need to transition references that look like:
https://storage.googleapis.com/tekton-releases/...
to the new format:
https://infra.tekton.dev/tekton-releases/...

Acceptance Criteria

• Documentation: Update all release and installation URLs across the docs/ folder, README.md, and any other markdown files.
• Scripts: Update any fetching, setup, or release helper scripts (e.g., inside the hack/ directory).
• Codebase Validation: Ensure that no broken links are introduced and that the updated infra.tekton.dev URLs resolve properly for Tekton Results manifests/components.
