[qmk] key override signature change in latest qmk

[meras]

Currently the miryoku_qmk fork seems to be behind the main qmk repo. I ran into a few issues when using an external userspace with latest qmk to compile miryoku.

I've not seen this mentioned elsewhere so I'll leave this here if anyone runs into the same issue.

The 2024 August 25 qmk release has a breaking change which affects /users/manna-harbour_miryoku/manna-harbour_miryoku.c#L56-L59

The fix is simple and provided in the changelong. In the above file change:

const key_override_t **key_overrides = (const key_override_t *[]){
    &capsword_key_override,
    NULL
};

to:

const key_override_t *key_overrides[] = {
    &capsword_key_override
};
