Fix accessibility of PR links in blog post

[Copilot]

The "Announcing TypeChat 0.1.0" blog post contains two links with text "see PR" that fail WCAG 2.4.4 - screen reader users cannot determine link purpose without surrounding context.

Changes

Updated link text in site/src/blog/announcing-typechat-0-1-0.md:

• [see PR](https://github.com/microsoft/TypeChat/pull/147) → [see PR #147 for TypeChatJsonProgram changes](https://github.com/microsoft/TypeChat/pull/147)
• [see PR](https://github.com/microsoft/TypeChat/pull/221) → [see PR #221 for processRequests changes](https://github.com/microsoft/TypeChat/pull/221)

Screenshot

Links now convey their purpose independently, improving accessibility for screen reader users and general usability.
