chore(ci): Reduce e2e attempts from 3 to 2 in CircleCI

[legobeat]

Description

This reduces:

• E2E CI retries from 2 to 1 (ie attempts 2 times instead of 3 times)
• The average cost and time to run individual CI jobs
• Feedback loops for e2e errors
• Success rate (and therefore hopefully introduction rate) of flaky tests
• Success rate (and therefore hopefully introduction rate) of inconsistent application behavior which relies on specific CI conditions to pass E2E tests

Non-E2E CI jobs have their existing retry count unchanged.
