Browse Source 
## Issue Addressed

Updates discv5

Pending on
- [x] #3547 
- [x] Alex upgrades his deps

## Proposed Changes

updates discv5 and the enr crate. The only relevant change would be some clear indications of ipv4 usage in lighthouse

## Additional Info

Functionally, this should be equivalent to the prev version.
As draft pending a discv5 release
