docs: fix broken TOC anchor and dead internal link in CONTRIBUTING.md

[Goutham-Annem]

What type of PR is this?

/kind documentation

What this PR does / why we need it

Two issues in CONTRIBUTING.md:

1. The Table of Contents has a [Testing](#testing) entry, but no ## Testing heading exists in the document — the link is broken.

2. Line 63 has [Contributing](#contributing) which is a useless self-link that points back to the document's own title. It should point to the ## Contributor Workflow section, which describes the actual PR workflow.

Which issue(s) this PR fixes

Fixes #7644
