Cannot disable Next button

[okamaw]

Hello,

I found a bug in form-wizard-vue3.
I would like to disable the button if all the mandatory fields are not filled up.
I disabled the next-button option but the button is still active.
I have a look at your source code, src/components/Button.vue, and found that :disabled=options.disabled.
But you cannot disable the button with this code as a button tag only takes "disabled" option, it does not matter if it were true or false.
Could you check it and fix the bug if possible?
