[Installer] Load gem plugins when installing

[segiddins]

Closes #2824 I think

[indirect]

@segiddins what's the difference between load_plugins and load_env_plugins, and why did you switch from one to the other?

[segiddins]

Because that seemed to be what the issue was asking for

[indirect]

@segiddins I am fairly certain it is not okay to remove load_plugins. Please either use both or research to figure out what the "right" (ha) answer is.

[segiddins]

Where did I remove load_plugins? Honestly, if we don't know what www want to do, I'd rather not touch this. I was just making the exact change the linked issue asked for ¯_(ツ)_/¯

[indirect]

I'm not comfortable accepting this until we understand the difference between load_plugins and load_env_plugins, so I'm sure that this change doesn't break anything.

[segiddins]

load_plugins loads all rubygems plugins and is what rubygems does when invoked via its own CLI, load_env_plugins just loads plugins that are already on the $LOAD_PATH

[indirect]

@segiddins okay. I hope we don't regret this later when it turns out there are rubygems plugins that we don't actually want to load. 😅
