Yeap - that is exactly what it does ;)

Example:

uses: ncipollo/release-action@440c8c1cb0ed28b9f43e4d1d670870f059653174 #v1.16.0

And for anything that previously had @master, it becomes the following with the hash on the day it was pinned with "master-{date}" as comment:

uses: ravsamhq/notify-slack-action@b69ef6dd56ba780991d8d48b61d94682c5b92d45 #master-2025-04-04
