Subject: [PATCH] Eslint config: migrate to the new
 'flowtype/use-read-only-spread' rule

This change finishes a migration from our custom `adeira/flow-use-readonly-spread` rule to the official `flowtype/use-read-only-spread` rule. The behavior should stay unchanged since the underlying code is basically identical. See: https://github.com/gajus/eslint-plugin-flowtype/pull/472
