Subject: [PATCH] feat(ansi): use `_` in short name and rst -> reset (#15907)

# Description
I've noticed that unlike everything else in nushell the output of `ansi
--list` has a column named `short name` instead of `short_name`, so I
changed it. While I was at it, I also added a shortname `rst` to `reset`
since it is often used.

# User-Facing Changes
Changed the column name of `ansi --list` from `short name` to
`short_name`
