Fix latest release download URLs (modelcontextprotocol#677)

Versioned release download URLs use a pattern like:


https://github.com/modelcontextprotocol/registry/releases/download/{version}/...

But latest release download URLs use a pattern like:


https://github.com/modelcontextprotocol/registry/releases/latest/download/...

For example:
https://github.com/modelcontextprotocol/registry/releases/latest/download/mcp-publisher_darwin_arm64.tar.gz

Fixes modelcontextprotocol#673.
