Summary

We should do a better job of documenting how to display a list of all modules loaded by spack load. This may require documentation in multiple places, including references in other commands, tutorials, and reference docs. Basically anywhere that we mention that spack load exists.

Rationale

This is probably the second most common question I see on Slack/GitHub after #22287.

Description

The correct command is spack find --loaded, but this isn't obvious to a lot of people, myself included.

Additional information

General information

• I have run spack --version and reported the version of Spack
