Update .env-local to work locally

.env file which worked for me to start things locally.

docker:go script didn't work for me, there were errors with npm, I'm not sure what's wrong.

I think it would be nice to include tl;dr setup for running the API locally, so for me it worked with this:

• Commited file here, renamed to .env
• Run docker:bare:up
• Run start:dev

Also, Paulius told me there is this swagger endpoint /docs, I think it would be nice to include this in the readme, as "After running tl;dr setup, you can preview available endpoints in /docs" or something.
