Update dev container configs to use aspire certs instead of dotnet dev-certs

[davidfowl]

Summary

The dev container configurations in get-started/dev-containers.mdx use dotnet dev-certs https --trust in postStartCommand/postCreateCommand. These should be updated to use aspire certs trust instead.

Locations

• src/frontend/src/content/docs/get-started/dev-containers.mdx — 6 instances across multiple devcontainer.json examples

Notes

• The Aspire CLI needs to be available in the dev container image for this to work
• May require updating the dev container feature/image to include the Aspire CLI
• aspire-sdk-templates.mdx also has one instance that should be updated at the same time
