Emphasized Button not bold

[mengbingguo]

The emphasized button doesn't show bold text style in React and it's a deviation from UI5 / Fundamental Styles.
Reason: Actually font-weight: 700; is set on the Button component, but it's overwritten by button text style font-weight: 400;

This problem occurs in NGX too. I already create an issue for that: SAP/fundamental-ngx#4078
