bun.sh/test/config/bunfig/fixtures/preload/multi

Used to test 3 behaviors:

1. preload can be an array
2. When a bunfig is specified via --config=<path>, the "default" bunfig (i.e. bunfig.toml in the same dir as cwd) is not loaded.
3. Using --preload <file> adds <file> to the preload list without clobbering existing preloads.
