Breaking: #75708 - Always store <p> tags in DB from RTE

See forge#75708

Description

When transforming HTML data from the Rich Text Editor to the database, the RteHtmlParser removed <p> tags from lines when there were no attributes for the <p> tags, otherwise they were kept as <p> tags with their attributes.

The transformation now always keeps <p> tags within the content in order to minimize the transformation overhead between the RTE and the database.

Impact

Every time an RTE field is edited, the <p> tags are now stored inside the database when saving the content.

Affected Installations

All installations using RTE fields or RteHtmlParser transformations.

Migration

An upgrade wizard inside the Install Tool (coming until 8.1) will make sure that any database RTE field is converted.
