This change reduces the CPU consumption of --help by ~50%.
Also, this change removes ANSI escape codes from our golden files. I
don't think those were worth the inability to parallelize golden file tests and
global state fragility.
* feat: add display_name field to groups
This is a non-unique human friendly group name for display
purposes. This means a display name can be used instead of
using an environment var to remap groups with OIDC names to
Coder names. Now groups can retain the OIDC name for mapping,
and use a display name for display purposes.
