Bump default checkpoint sync timeout to 3 minutes (#4466)

Browse Source 
## Issue Addressed

[Users on Twitter](https://twitter.com/ashekhirin/status/1676334843192397824) are getting checkpoint sync URL timeouts with the default of 60s, so this PR increases the default timeout to 3 minutes.

I've also added a short section to the book about adjusting the timeout with `--checkpoint-sync-url-timeout`.

### Adjusting the timeout
If the beacon node fails to start due to a timeout from the checkpoint sync server, you can try
running it again with a longer timeout by adding the flag `--checkpoint-sync-url-timeout`.
```
lighthouse bn --checkpoint-sync-url-timeout 300 --checkpoint-sync-url https://example.com/ ...
```
The flag takes a value in seconds. For more information see `lighthouse bn --help`.
