chore(binaries): Small tweaks for latest reth and lighthouse.

[ryanschneider]

• Lighthouse dropped the "-portable" suffix as of 5.3.0, now all the image are "portable"
• They also now require the --suggested-fee-recipient when running bn as well, I copied the same recipient as the validator.

However, keeping this a draft until I figure out why the bn isn't synced in time:

Stopping reth
Stopping beacon_node
Stopping validator
Error: failed to create relay: beacon client failed to start

Edit: it must be some other change to LH, seems to be coming up on the wrong fork:

Edit 2: After diffing the two logs, these are all the log lines that are included in the 5.3.0 log that aren't in 5.2.1:

Edit 3: Ok, I got confirmation from the lighthouse team that 5.3.0 has some regressions for single node testnets like ours that our fixed in unstable. I was able to confirm that using a self-built version of lighthouse unstable alongside --use-bin-path works with the changes in this PR, so I think I'll just keep it a draft until there's another LH release.

I pulled everything necessary from this into #37.
