refactor(iroh-net)!: Rename the local-swarm-discovery feature to discovery-local-network (#2634)

## Description

Rename the local-swarm-discovery feature to discovery-local-network to
be consistent with discovery-pkarr-dht

## Breaking Changes

renames the `local-swarm-discovery` feature flag in iroh-net to
`discovery-local-network`

## Notes & open questions

Naming is hard. Pretty sure the ff should start with `discovery-`, but
should it be `discovery-local-network` or `discovery-local-swarm` or
just -local...?

## Change checklist

- [ ] Self-review.
- [ ] Documentation updates following the [style
guide](https://rust-lang.github.io/rfcs/1574-more-api-documentation-conventions.html#appendix-a-full-conventions-text),
if relevant.
- [ ] Tests if relevant.
- [ ] All breaking changes documented.
