Update Semantic Router release status

This recap is dated June 25, 2026, but the repo already has _posts/2026-06-05-v0.3-vllm-sr-themis-release.md announcing vLLM Semantic Router v0.3 Themis as released; saying only two major releases have shipped and then describing Themis separately makes the new post stale on publication. This should list Themis as the third shipped release, or otherwise align with the June 5 release post, so readers are not told the latest release has not shipped.
