feat: Add team label to pr

[itsyoboieltr]

Description

This PR adds the add-team-label GitHub workflow and the accompanying add-team-label-to-pr script. Most of the implementation follows the add-release-label GitHub workflow and the add-release-label-to-pr-and-linked-issues script. To make the implementation easier, a new helper function, addLabelByIdToLabelable was also added, and the previously non-exported retrieveLabel function was exported.

When a new PR is opened, it will automatically add the author's team to the labels.
