Description of changes

Fix e2e tests and view-test-artifact command

• all of the auth and geo e2e tests were broken by the first iteration of the fix for the regression, created a new iteration of a fix for the auth and geo categories that is compatible with our e2e tests (also manually tested that it works to fix the regression)
• downgraded baseline python version for lambda functions back to 3.8, decided it was not work the effort to fix the remaining broken test for this release
• view-test-artifact command was being pretty temperamental and only wanted to work properly after running yarn clean, made a change to make it more stable - have used it several times since and it has been working well

The only failing e2e test is known to be flaky and has to do with the notifications category, unrelated to the changes in this PR.
