build: lint-staged prettier before eslint (#4445)

prettier autofixes some issues eslint finds, letting prettier run first
leads to less developer hassle

for example, I've forgotten for weeks to change how my editor does tabs
instead of spaces and I've been manually running `npm run fmt` to get
around this. While yes I will also correct my editor, this feels like a
positive change for all contributors
