Replacing system-wide `nodejs` by another version managed by `nvm`

Some legacy codes are not compatible with latest nodejs. nvm helps with this situation to provide older stable version.

Uninstall system-wide nodejs and install nvm via package management.

Config fish-shell:

function nvm
   bass source (brew --prefix nvm)/nvm.sh --no-use ';' nvm $argv
end

set -x NVM_DIR ~/.nvm
nvm use default --silent

Take effect immediately:

source ~/.config/fish/config.fish

An extension to fish-shell is bass.

Bass makes it easy to use utilities written for Bash in fish shell.

An extension to homebrew is cask.
