Incorporate second round of feedback from lightblocks

[samlaf]

lightblocks shared this feedback with us:

• BLS apk registry is assumed to exist on the registry coordinator, if it does not exist then the error displayed does not describe that the BLS apk registry is missing
• Quorum numbers displaying “AA==” instead of [0] for us
• After “Transaction not yet mined” tx hash, another tx hash is printed however the “not yet mined” hash is the one executed

This PR fixes all 3. Only quorums is fixed here. The other 2 were bugs in sdk, which I am waiting for those PRs to be reviewed and merge before updating the sdk version in this PR to get those changes in: have been merged

• added error logs for avs reader/writer clients eigensdk-go#115
• we were printing tx hash of half-built transactions, which was pointless eigensdk-go#114
