🔥♻️ Use recommended image + use standard script

- The alpine build-kit is now deprecated, use the recommended
  one
EVerest#78 (comment)

```
---------------------------------------------
WARNING
This docker image is depreacted.
Please use the debian based build-kit 'ghcr.io/everest/everest-ci/build-kit-base' instead.
Fore more information see EVerest/everest-ci#22
---------------------------------------------
```

- Now that there is a standard install script, instead of
  only test-and-install, so that we can roll forward

EVerest#78 (comment)

Testing done:
- Built successfully using a container
- Ran the `everest-demo/docker-compose.yml` and
  `everest-demo/docker-compose.iso15118-dc.yml` scripts. Both
  worked.
- Testing `everest-demo/docker-compose.ocpp201.yml` fails because go is running into SSL issues on my work laptop. Need to figure out how to resolve that
