Investigate increasing Maintainer Productivity with Pull Requests Environments

[waveywaves]

I would like to make life easier for HTTP Prompt maintainers by implementing Uffizzi
previews.
Disclaimer: I work on Uffizzi
Uffizzi is a Open Source full stack previews engine and is completely free for HTTP Prompt (and all open source projects). This will provide maintainers with previews of their PRs in the cloud, allowing them iterate faster and reduce time to merge.

TODO:

• Intial POC
