Reliability score edits from Fed and Tatiana

Edited reliability score description making it more broad saying it's applicable to purity of DIA detections instead of just transients.

Adding Fed and Tatiana to credits.

This score is computed using information from the source and image characterization, as well as the information on the Telescope and Camera system. However, given that the reliability score model was trained on a relatively small and limited dataset, some caution is warranted in interpreting the `reliability` score in DP1, in particular for variable stars. Significant improvements are expected on future releases with LSSTCam data."
