🔧 No SDCARD_SORT_ALPHA on Creality CR-6 SE (for now)

[thisiskeithb]

Description

While running the build_all_examples script, this config would not build because SDCARD_SORT_ALPHA was enabled:

#error "SDCARD_SORT_ALPHA requires an LCD that supports it. (It doesn't apply to M20, etc.)"

I see the upstream PR (https://github.com/MarlinFirmware/Marlin/pull/19958) uses this config and is passing upstream CI tests, but it's been open for four years and has caused CI to fail in this (Configurations) repo since we've enabled CI testing on all PRs. If CR-6 SE support is ever merged, we can enable SDCARD_SORT_ALPHA on this config again.

Benefits

Config now builds.
