refactor(go): upgrade go-retry to v5 and enable infinite reconnection

[chengxilo]

Which issue does this PR close?

N/A

Rationale

Upgrade retry-go to v5, since I just realized that v3 will crash when the WithAttempts() receive a big uint value, e.g. math.MaxUint32.

Also, to align with the rust client behavior, go sdk should have infinite retry for reconnection.

What changed?

1. retry-go version upgrade to v5.
2. Default attempts set to 0, which means infinite for go-retry
