[TYPO3-doc] Tip for ReST editor: Styles for screenshots

[Fabien Udriot]

Hi Martin,

>> Recommendations:
>>
>> - don't use :width: and :height:
>> - use :class: screenshot-detail for "small to medium" screenshots
>> - use :class: screenshot-fullsize for "large" screenshots

Thanks for the info,

I don't have the time right now but that would be cool if someone could add the info into the
Extension Manual Example.

All the best,
