Missed "system" gems when upgrading (Mac)

[pdelre]

Quick disclaimer: I'm not a ruby dev, so I might be missing some key context.

When running mpm outdated and system level gems are listed out of date, a subsequent running of mpm upgrade does not update those gems. This appears to be due to mpm update using --user-install, while there does not seem to be the same option for the outdated command.
