[v4] InputNumber: Missing type declaration for buttons leads to form submit on button click

[m-meier]

Describe the bug

In PrimeVue v4 the InputNumber component uses normal html button elements for increase/decrease buttons. However, they lack a type specification. This leads to the problem that clicking the buttons will perform a form submit when placed within a form. This behavior might be browser specific, but is reproduceable in Google Chrome on Windows

According to the w3c spec: The attribute's missing value default and invalid value default are both the Submit Button state.

Steps to reproduce the behavior
