Add log downloading for sync integration tests

[smartcontracts]

Is your feature request related to a problem? Please describe.
Seems like we've recently added sync tests to our integration tests: https://github.com/ethereum-optimism/optimism/blob/develop/.github/workflows/sync-tests.yml. However, the sync tests do not upload the logs as artifacts to GitHub like the integration tests do. This makes it very difficult to debug the tests.

Describe the solution you'd like
I'd like to see these lines added to the sync tests:

optimism/.github/workflows/integration.yml

Lines 97 to 113 in c87e4c7

	if: failure()
