Skip Gem::Deprecate Warnings; The CLI handles that 🛀

Description

When running a fakerbot command in verbose mode e.g. fakerbot list -v fakerbot actually invokes fakers methods; even ones with deprecation warnings.

When this happens faker will by default print the deprecation warnings. We don't really want that as the CLI is already showing deprecation warnings as handled in #10
