fix: make "ipfs resolve" cli command recursive by default (#3707)

This changes the default behaviour of the `jsipfs resolve` cli command to be recursive by default. Closes #3692.

```shell
# in packages/ipfs
node src/cli.js resolve /ipns/ipfs.io
/ipfs/bafybeiagozluzfopjadeigrjlsmktseozde2xc5prvighob7452imnk76a
```
