Based on this spec: https://github.com/dotnet/aspire/blob/main/docs/specs/connection-properties.md

Find all /integrations/**/*.mdx that exist, that define connection properties and add content for them. For each integration name defined in src/frontend/src/data/aspire-integration-names.json try fetching the
https://raw.githubusercontent.com/dotnet/aspire/refs/heads/main/src/{integration-name}/README.md and looking for Connection Properties, and then using that info to add to the corresponding article's hosting integration section.
