fix(mise/ruby): move global gems back to shell helper

Mise is only suitable for gems which expose self-contained CLI tools that don't interact with other Ruby-based tools.

Because it sets GEM_HOME to the specific gem's install path, things like `foreman` cannot launch Rails apps, cause any Ruby-based child processes will not find any gems they expect.
