Update to latest schema version 2025-10-17

What does this PR do?

The MCP Registry has iterated the schema version two more times, and has now locked it as a "v0.1". Fortunately this new schema version does not actually impact us but the MCP Registry does assert the new schema URL.

See https://github.com/modelcontextprotocol/registry/blob/main/docs/reference/server-json/CHANGELOG.md
