[Keymap] Add keymap for the Keychron Q1 ISO layout (#14853)

* Add keymap for the Keychron Q1 ISO layout

- The rightest key column is: Ins, Home, PgUp, PgDn, which differs from the default.
- RGB lighting turns off when the computer sleeps
- Caps Lock and alpha keys turn red to indicate when Caps Lock is on
- When the Fn layer is active, RGB lighting turns off for keys that are not assigned

* Update keyboards/keychron/q1/rev_0102/keymaps/kubahorak/rgb_matrix_user.c

Suggestion from review

+# kubahorak's Keychron Q1 keymap
+
+This ISO layout got heavily inspired by gtg465x's ANSI keymap (rev_0100).
+
+Features:
+- The rightest key column is: Ins, Home, PgUp, PgDn, which differs from the default.
+- RGB lighting turns off when the computer sleeps
+- Caps Lock and alpha keys turn red to indicate when Caps Lock is on
+- When the Fn layer is active, RGB lighting turns off for keys that are not assigned
+
+## Changelog
+
+### 2021-10-17 - 1.0.0
+
+- Initial release
