Python 3.13.0b1 REPL does not travel words when pressing Ctrl+← or Ctrl+→

Bug report

Bug description:

When I type this to older Python REPLs:

>>> text = "I can travel the words."

And I press Ctrl+←, my cursor moves in front of w. I can press Ctrl+← again to go in front of the t etc. I can then press Ctrl+→ to travel the words in the other direction. My bash behaves the same. Again, I don't know if this is Fedora's configuration of readline, or the default.

In Python 3.13.0b1 REPL, this no longer works. Pressing Ctrl+← or Ctrl+→ seemingly does nothing.

CPython versions tested on:

3.13
