Bug report

Bug description:

According to the Windows spec, the locale identifier for Cambodian (0x0453/1107) should be "km-KH"

Sources:

• https://learn.microsoft.com/en-us/openspecs/windows_protocols/ms-lcid/70feba9f-294e-491e-b6eb-56532684c37f
• https://ss64.com/locale.html

Currently locale.windows_locale[1107] == "kh_KH" incorrectly.
https://github.com/python/cpython/blob/3.12/Lib/locale.py#L1596

It is possible this mistake is from an older version of the protocol, but using the MS reference, the current mapping in Windows has been the case since the earliest recorded spec from 8/8/2013.

If this issue is accepted I am happy to make a small PR to adjust this value.

CPython versions tested on:

3.11, 3.12, 3.13, CPython main branch

Operating systems tested on:
