Update zmk version

[anoburn]

I changed the zmk version we use back to "main" and adapted the rest of our code to the changes. This boils down to:

• changing "label" -> "display-name" and "tapping_term_ms" -> "tapping-term-ms"
• removing LVGL_HOR_RES_MAX and LVGL_VER_RES_MAX and updating LVGL-names to LV (see https://zmk.dev/blog/2023/04/06/zephyr-3-2#lvgl-kconfig-changes )
• adapted usage of SSD1306_REVERSE_MODE (see https://zmk.dev/blog/2024/02/09/zephyr-3-5 )

I see only one concern (see comment on the west config). Everything else looks good.

Can you set the version in the config to match the current 'main' so we don't run into build issues in the future and its clear exactly which version of zmk is being used for ardux builds?
