Bug#1020237: pokerth-data: depends on gsfonts-x11 should be replaced by fonts-urw-base35

[Andreas Beckmann]

Followup-For: Bug #1020237
Control: severity -1 serious
Control: tag -1 sid bookworm

Raising the severity since there are some broken symlinks aka missing
fonts with the transitional gsfonts-x11 package (which does not have the
"numerical" font names):

0m22.1s ERROR: FAIL: Broken symlinks:
  /usr/share/games/pokerth/fonts/c059013l.pfb -> ../../../fonts/X11/Type1/c059013l.pfb (pokerth-data)
  /usr/share/games/pokerth/fonts/n019003l.pfb -> ../../../fonts/X11/Type1/n019003l.pfb (pokerth-data)
