Temporarily disable retries in docker build tasks (#96256)

Related to https://github.com/elastic/elasticsearch/issues/96207, I
believe our retry logic is either a) contributing to weird failures or
b) masking the root cause of failures in our Docker builds. I'm
temporarily disabling this for now to try and get some better
diagnostics.
