Palettes Dialog and Palette Editor: Update to 2.99
- Remove non-existing "Save" and "Revert" Palette Editor bottom panel buttons. According to https://gitlab.gnome.org/GNOME/gimp/-/commits/master/app/actions/palette-editor-actions.c they have never existed.
- Clarify that "accessible by right-clicking in the palette display area" only works when actually clicking on a color and not the surrounding empty area.
- Rephrase "Offset" section for clarity.
- Rephrase "Ascending" section as it's a checkbox now and not a dropdown.
- Replace "at the time of writing" which no reader can know with "as of 2024".
- Correct link to Palette Folders section in Preferences.
- Remove duplicated description of "Edit Color" option.
- Fix capitalization of "Channel to Sort" as in UI.
- Fix "Untitled " whitespace typo.
- Remove incorrect and trivial screenshot palettes-offset-options.png.
- Remove trivial screenshot palette-editor-context-menu.png: it depicts a single menu and all its menu options are listed right below as text.
- Update screenshot palette-editor-dialog.png (less buttons in bottom panel, "Undefined" is now "Untitled").
- Update screenshot palettes-context-menu.png (two instead of one menu structure).
