fix: decode html entities correctly (#8047)

fixes #8026

1. replace the big entities list with entities that have a ; at the end where valid (there are some exceptions)
2. construct two regexes from that entities list: one for HTML where it's strictly matched, one for attributes where it tries to match browser behavior by also allowing = / digit / character afterwards
3. decode character references with one of these regexes depending on this is an attribute value or not
