Browser > Explore sites > default resource link issues

Not sure who owns the content for these default resources on the browser but may need to coordinate with whoever does.

- AirSwap URL does not look like it exist anymore, need to find updated URL or remove if no longer exist
- Radar Relay URL does not look like it exist anymore, need to find updated URL or remove if no longer exist
- Tokenlon does not have MetaMask as a selection to connect wallet, we can reach out to them or consider removing

- Chainlist logo is broken

No file, test, or entry point is named; start by locating the browser's default Explore sites resource definitions and checking each listed link and logo. Done means confirming replacement URLs or removals for unavailable resources, resolving the Tokenlon and Totle wallet-connection concerns, and fixing or replacing the Chainlist logo.
