Subject: [PATCH] fix(ci): make aztec-up verdaccio prime retry patiently

The aztec-up test primes a local verdaccio registry by running
'npm i -g @aztec/aztec ...', which resolves every transitive dependency
fresh from npmjs. A transient upstream/registry miss can 404 a single
uncached version even when it is published (observed on merge-train CI:
@aws-sdk/credential-provider-env@^3.972.46 404'd although it had been
published ~13h earlier). The default retry (3 attempts, 5s apart) is too
impatient to ride out the blip and dequeued the spartan-v5 merge train.

Retry the prime up to 8 times with 30s backoff before failing.
