Dev2 environment setup

[ncgreene]

For now .env/dev2.json exists, but there is more work to be done if we want this environment to be useful.

Tasks

• Add dev2.ottehr.com to vercel
• Create dev2 github environment and add dev2.json to github secrets
• Update package.json and build-and-deploy scripts to support dev2 deployments

It's also worth noting that dev2 environment points to zapEHR's testing environment
