251 backoff verbosity

[LucaCinquini]

Purpose

• Reduce the verbosity of the logs when executing tests, which now it's making debugging failed tests pretty difficult

  Proposed Changes

• Change the parameters of the @backoff decorator to reduce the number of failed attempts, and stop logging unnecessary output

  Issues

• https://github.com/unity-sds/unity-sps-prototype/issues/251

  Testing

• See result of failed tests when using this branch: https://github.com/unity-sds/unity-sps-prototype/actions/runs/7399949377
