feat: Improve depTypes configuration (#577)

depTypes configuration is now refactored from being an array of strings/objects to having each type of dep (`dependencies`, `devDependencies`, `optionalDependencies`, `peerDependencies`) be a first class object in the namespace. The "old" way of configuring is still supported but is transformed using a migrateConfig script. Later, PRs will be raised to impacted repositories to suggest the new config.
