Can we add retries for CI?

Context:

When we fetch dependencies we were getting 4xx errors because they didn't show up in the module mirror and checksum database (there's a bit of a delay). To avoid this we turned off using the mirror and the checksum db. Doing this opens us up to a potential supply chain attack - since we aren't verifying the sums.

Settings are here: https://go.dev/ref/mod#checksum-database

I think the env var settings let you tweak which modules we do verification on - that could be an minimal option here.
