test-matrix: Fix failure with artifact redirects.

GitHub's API is now redirecting requests to download GHA artifacts
to https://productionresultssa0.blob.core.windows.net/. This service
rejects requests that contain an Authorization header, breaking our
publish-website.yml workflow. octocrab should not be sending this header
when redirected, and I have filed
XAMPPRocky/octocrab#562 to address the bug.

Until that PR is merged, we can work around this issue by enabling
octocrab's "follow-redirect" feature, which configures the tower
middleware to handle the redirect instead of octocrab, which (correctly)
doesn't include the authentication header in the redirected requests.
