Optimize RTE page

[sypets]

Main point it to add examples for setting a preset via page TSconfig.

Additionally, the following changes are made:

• add a header for the examples (since examples are now extended and this improves finding the examples when skimming the page)
• add clarification what "order" (for the presets) means. If not familiar with TYPO3 one might assume, the order means that the later settings overrides the previous which is not the case: once a setting is set, the ones following it are ignored.
• clarify what default (number 4. in the listing of "order") means
• add some links

---

Note to reviewers:

• I have not set the backport labels. I think this can be backported as is, but should double check
• Please check if this actually improves the clarity. I found some parts to be a little vague but adding extra text always has the problem that it clutters up the page and makes it less terse which might even impact the clarity negatively
