feat!: bump node engine requirement >=20.5.0 & update deps (#1528)

cordova-ios 8.0.0 was already targeting NodeJS 18.x and that's EOL as of
next month, so we might as well just bump this to 20.x and update to the
latest version of nopt and which. This also matches the version bump
going in to the next cordova-android major.
