Improve example development .env files (#1107)

* Add comment to explain how each one is intended to be used
* Use a correct value for `VUE_APP_API_URL` env var
* Use more sensible values for `VUE_APP_CNAME_RECORD` and `VUE_APP_SUBDOMAIN_SUFFIX` env vars
* Remove confusing `# todo replace with test key` comment
