fix: docker image errors

Docker image builds > 1.2.0 do not work at all, they fail to execute
optic-ci. Example:

```
$ docker run --rm snyk/sweater-comb:1.2.2 --help
internal/modules/cjs/loader.js:905
  throw err;
  ^

Error: Cannot find module '@babel/runtime/helpers/interopRequireDefault'

Adding babel.config.js and the babel runtime as a package dependency
seems to fix this issue.

Also added schemas to the image build -- similar issue was fixed in the
package.json
[here](https://github.com/snyk/sweater-comb/pull/176/files#diff-7ae45ad102eab3b6d7e7896acd08c427a9b25b346470d7bc6507b6481575d519R12),
but also needed in the image build as well, since we're
stripping it down.

Updated runtime image base to alpine. It's a little bigger, but
distroless was too hard to debug without a shell and its still under
200MB.
