Emacs master not update automatically

[Eason0210]

The automatic update of the emacs repo seems not work. The last commit with the description Updated repos/emacs was f2c57ef , committed 12 days ago.

Now, Emacs master has been updated to 29.0.50.

See #172; it was failing to update because we gathered only the last 6 months' worth of commits and searched for some tag within that timeframe.

Right now, other stuff is not updating either. I'm guessing it's due to recent Org updates, I'll look at it later.
