Minor fix invalid type when running docker-compose

[dondasasmita]

Thanks for taking the time to review this PR.

Background

While runnning docker-compose up -d, I encountered the following error

WARNING: The ENBIZCARD_PORT variable is not set. Defaulting to a blank string.
ERROR: The Compose file './docker-compose.yml' is invalid because:
services.app.ports contains an invalid type, it should be a number, or an object

This issue was created because I ran the previous command cp env-example .env, which will copy and create the .env for docker.

Changes

• A minor fix is done on the env-example to avoid others running into the same issue. Changing : to =
• docker-compose.yml is auto formatted since there is a prettier config, "singleQuote":true
