Suppress innocuous error message from tag determination

The taskfile uses a Git command to get the current tag name. When there is no tag, it produces an error message every time a task is run:

fatal: No tags can describe 'a58dfe994fdd94aa98ccc98b327d49f347384c2f'.
Try --always, or create some tags.

This error message is expected and doesn't impact the functionality of the taskfile, but it might cause confusion. The
solution is to redirect the stderr from the command to /dev/null, which won't affect the functionality since the tag
name is output on stdout.
