Improve resilience of findAndConnect

[jacobheun]

Currently findAndConnect uses Promise.all to connect to all found providers, https://github.com/ipfs/js-ipfs-bitswap/blob/v1.0.0/src/network.js#L137. If we find multiple providers and for some reason fail to connect to 1 of them, findAndConnect will fail.

In reality we probably only need at least 1 to succeed so it might be better to use something like Promise.allSettled to avoid unnecessary failures.

The other promises aren't being aborted at the moment so it looks like this should still connect to available peers. As such, this likely isn't a big issue at the moment, but it should still be fixed.

Hello, is this still open? I'm thinking if the satisfaction is for any of them to fulfill then wouldn't Promise.any be a better choice?
