fix: docker image

[alesbrelih]

Changed docker image from scratch to golang because with golang/x/tools lift from v0.26.0 to v0.27.0 there was a breaking change of retrieving golang env variables using go executable.

Which breaks ogen in scratch image as go isn't available.

Nevermind, went a bit deeper into the rabbit hole.
Autoimports were already enabled. Problem is that they added an additional logic when checking imports to be fixed inside:
getFIxes func. Now they invoke go to get go env variables using goEnv, err := env.goEnv(). Relevant MR: golang/tools@cceaf96#diff-05cab7fa801ce49d3d9a722a26809eb264b04da83e4a667a1100793ff2e9bdbbR572

Changes are in internal/imports/fix.go so it doesn't automatically jumps to diff. You need to expand it first.

I see no other way than moving from scratch image from the moment.

Closing because it was already fixed on main branch.
