nu: Start setting up new nushell config

Browse source 
Remove most of the old cruft that was left over from nushell version
0.87 - we are now on version 0.102!

Many of the old options are actually not helpful anymore so let's just
get rid of them entirely (never configured the shell for me too much).
Also there was a lot of 'default' commented code which made it harder to
keep an overview rather than help.

For now just set up a minimal shell experience with vi editing mode, and
the trifecta of startship prompt, zoxide movement and atuin history
enabled.

# version = "0.102.0"
#
# # Perform tilde substitution on dir
# # To determine if the prefix of the path matches the home dir, we split the current path into
# # segments, and compare those with the segments of the home dir. In cases where the current dir
# # is a parent of the home dir (e.g. `/home`, homedir is `/home/user`), this comparison will
# # also evaluate to true. Inside the condition, we attempt to str replace `$home` with `~`.
# # Inside the condition, either:
# # 1. The home prefix will be replaced
# # 2. The current dir is a parent of the home dir, so it will be uneffected by the str replace

# if ($env.PWD | path split | zip ($home | path split) | all { $in.0 == $in.1 }) {

# In general, most configuration can and should be performed in `config.nu`
