Update texmaker to version 5.0.3 .

Removed poppler-qt5 dependecy since it uses pdfium instead.

version 5.0.2 -> 5.0.3 :
- the bug about the bad highlighting on misspelled text before a \cite{} or
  \label{} command has been fixed
- if no text is selected the "(un)comment" command will (un)comment the
  current line
- the default size of the configuration dialog has been reduced (users request)
- Fold/Unfold/Fold All/Unfold All menu options has been added
  (thanks to Robin Watts)

  been fixed

- the "-dpiscale x" option has been added to the Texmaker command line \
