Update documentation for importing PG dump
What
Updating documentation for importing PG dump locally in GDK and Docker.
Why
Docker process needs more steps for dropping DB and creating it using gitlab-psql
user, otherwise there will be an PG::InsufficientPrivilege: ERROR: permission denied to create database
error when running db_create
from the main gitlab
user.
