CKEditor 5 now respects row value within field widget settings

In previous versions of Drupal, the CKEditor 5 (and previously 4) WYSIWYG editor did not respect the rows value in the field's widget settings (for 4 there is only ckeditorheight in contrib). With this change, CKEditor 5 will now show an approximation of the configured number of rows.

Note that rows is really a monospaced <textarea> concept, and only in that context can it work precisely. In the case of CKEditor 5, the line height of each line can be different — for example a subheading versus a paragraph, etc. The approximation algorithm Drupal applies to CKEditor 5 to make the rows setting apply approximately relies on a paragraph's line height and margin.

The default for text fields' widgets is rows=5, which looks like this
