docs(website): fix 4 drifts caught by cross-check against atmosphere repo

A2A spec moved from google.github.io/A2A (404) to a2a-protocol.org under Linux Foundation stewardship; bump Quarkus floor to 3.35.2+ to match pom.xml and the main README; drop unverified "first Java framework" superlative from the WebTransport pillar (native WebTransport support stands on its own); correct enterprise-support start year 2014 → 2013.
