[go] clean up gen of go types

[akosyakov]

Description

In context of #15062 we need to pass config from server to ide-service.
But because of current code generator we cannot unmarshall it and marshall back additional tasks.
This PR simplifies code generated output that it has only types and rely on default go logic for marshalling.

@geropl webapp team is assigned, but only IDE team is using it 😄 I asked @iQQBot to test

@iQQBot feel free to unhold if IDE still can parse yaml

To what extend do we control the gitpod-config-types.go generated code? Could we adjust the generator to generate more appropriate code for us? I don't have as much context on this so you may have already explored this.

@easyCZ We use github.com/a-h/generate. We could fork it, but I think this PR already does what we need.

maybe it's a good idea, we can fork this repo and do some change. cc @akosyakov

@iQQBot ok, it is up to you

Test with gitpod repo, it works

/unhold

we discuss we use this way first, and do a fork if we still need some advanced change
