Subject: [PATCH] fix: fix ssl behavior in `request`

- `ClientConnectionError` in `aiohttp` can wrap SSL handshake and
  certificate verification errors
- Retrying those hides the real cause and produced
  `TransientNetworkError` instead of the expected certificate error
- Removing `ClientConnectionError` from the transient list lets SSL
  errors surface correctly
