[Datasets] [GitHub] Adds GitHub Action for adding Datasets-labeled issues to Data Team project (#26127)

This PR adds a GitHub Action that adds datasets-labeled issues (upon opening/labeling) to the Data Team's GitHub project. This should obviate the need for manual issue adding to the project before the start of each sprint.
