zsh: Switch from powerlevel10k to pure prompt

Switched theme of zsh, just to declutter a little and make startup
slightly faster.

Removed nvm from automatically initializing to majorly speed up zsh
startup times - removing around 750ms on my system.
TODO could potentially move to a conditional startup system, in which
nvm only gets sourced on its first invocation or similar workarounds.
