Use <ab> instead of <p>

[tillgrallert]

By wrapping each page in a <p> element, this stylesheet assumes a semantic model that just doesn't correspond to the input. It would be better to use <ab> ("anonymous block" in TEI parlance) if one absolutely wants to wrap each page in a single element.

@tillgrallert Thanks for this very valid point.

I added an option for TextRegions that are explicitly typed as “paragraph” (e. g. by Transkribus).
