Summary

textproc/txt2tags: Update to 3.4, fix graphics/qgis and graphics/qgis-ltr with this newest version

• Use python3 only [1]
• Fix graphics/qgis and graphics/qgis-ltr with txt2tags-3.4 (remove --css-sugar --css-inside) [2][3]
  
  Changelog:
  
  https://github.com/txt2tags/txt2tags/blob/v3/CHANGELOG.md
  
  [1] txt2tags v3 can use python2 too. But, only graphics/qgis* uses it and depends on python3. I want to avoid adding dependencies. And python2 is dead, isn't it? ;) [2] https://github.com/txt2tags/txt2tags#feature-differences-between-versions [3] https://github.com/qgis/QGIS/issues/33516

Just a habit to iterate when there are several files to modify :)
I'll fix that.

Remove the loop
