"Czech (qwerty)" layout has " instead of ß in the 4th level

[Impact]
In precise, a new version of /usr/share/X11/xkb/symbols/cz appears. The alternative "Czech (qwerty)" layout redefines <AC11> key, overriding the definition of "Czech" (the base layout). Thus, there is no ß in that layout, making it unusable for writing German texts.

Not sure if this is a good place to discuss it, but the 3rd level of the czech layout contains all characters needed to write German texts; omission of ß in favor of " (which is in the 2nd level of AC10 already by standard) defeats that purpose.

[Fix]
Workaround is to change that key back to include "ssharp":

     key <AC10> { [ uring, quotedbl, semicolon, colon ] };
- key <AC11> { [ section, exclam, apostrophe, quotedbl ] };

     key <AD11> { [ uacute, slash, bracketleft, braceleft ] };
     key <AD12> { [parenright, parenleft, bracketright, braceright ] };

[Test Case]
1. In keyboard layout settings, set Czech (qwerty) layout
2. Hold the fourth level key (Shift+Windows or however you've configured it)
3. Hit the section key (§, 2 keys right of the L key on czech keyboards, or the ' key on us keyboards)
Broken behavior: " printed
Expected behavior: ß printed

[Regression Potential]
The patch only changes the czech keyboard layout, so the scope of regression risk is limited to that. This changes a specific key mapping; possibly some users may have gotten used to typing Shift+Windows+§ for ", but as mentioned in the bug report Shift+' gives the equivalent function with one fewer key press.
