Update sample configs for proper debounce entry

Update sample configs for proper debounce entry

While the Endstop module supports both `debounce_count` and
`debounce_ms`, the ZProbe module supports only `debounce_count`.

This commit updates all of the sample config files that included
`zprobe.debounce_count` to use `zprobe.debounce_ms` instead.
