Basic golang CI setup (#360)

* bskyweb: Makefile and dev env

This matches the setup for local dev testing in atproto and indigo
repos.

* gitignore: don't ignore self and .github/

* CI: golang build+test and lint actions

* bskyweb: better use of godotenv

A recent change from indigo.

* prettier: ignore top-level app.json

* CI: bump from golang 1.19 to 1.20

* bskyweb: update to golang 1.20
