Keymapping "page_{up,down}" and "half_page_{up,down}" doesn't work

Summary

When setting some keys to trigger the commands page_up, page_down, half_page_up or half_page_down, it doesn't perform any action in the editor, feels like a no_op.

Reproduction Steps

Tested on helix 22.12 and a compiled version from commit 0a7c697dd785111626c8f47a36e07381f55c2e83.

A minimal config to reproduce the bug:

[keys.normal]
q = "page_up"
w = "half_page_up"
e = "page_down"
r = "half_page_down"

page_up and page_down works on the latest master (commit 0a7c697dd785111626c8f47a36e07381f55c2e83) but not on 22.12

half_page_up and half_page_down doesn't work on both of the versions.
