Phoenix application in Gitpod

Sample application to develop Phoenix applications in Gitpod.

What's in the box?

1. Dockerfile based upon gitpod/workspace-full.
2. PostgreSQL 14
3. Compiles ElixirLS extension with the current Erlang/Elixir version to properly autocomplete when using the use macro. The extension is installed using a task in .vscode/tasks.json. Currently there is no other way to do this until you can define extensions via a local file path in .gitpod.yml.

Files to look at

1. .gitpod.yml
2. .gitpod.Dockerfile
3. gitpod/install_extensions.sh
4. .vscode/tasks.json
