Allow setting prefix/suffix for the value added to the element's dataset similarly to the class

Is your feature request related to a problem? Please describe.

I have a custom name for my daisyUI light theme and dark theme hnzelight & hnzedark, but the injected data-theme="..." is either dark or light. This prevents daisyUI to detect the appropriate theme. If I could add hnze as prefix, that would fix my problem. My alternative is to rename my light and dark themes to light and dark.

Describe the solution you'd like

Add a dataValuePrefix and dataValueSuffix as an configuration option and concatenate those with the value of the detected theme.

Allowing to pass a function could also add even more flexibility but that may be overkill.

Describe alternatives you've considered

My alternative is to rename my light and dark themes to light and dark for daisyUI.
