Increasing Qt dependency in master

[Pierre-Olivier Roy]

Hi everyone,

I am new here, I was using kdevelop for my project, since a few things were
bothering me (mostly differences in options between remote and local
debugging), I decided I would have look at the source code.

I managed to build kdevelop using kdesrc-build, which had issues with a
kdevelop qtwebkit dependency, since kdesrc-build uses Qt 5.15, and qtwebkit
is only available up to Qt 5.9. I had to manually compile qtwebkit 5.9
against qtcore 5.15 to get it to work.

Following qmake output if qtwebkit is missing:
-- The following REQUIRED packages have not been found:
 * Qt5WebKitWidgets, <https://qt.io/>
   QtWebKit, for integrated documentation
git show -> commit f124dab2c4423a1dfb5052c4c6fec276ac4bfb23 (HEAD ->
master, origin/master, origin/HEAD)

So about this version bump, is this qtwebkit dependency really required for
documentation? Clicking on User Manual opened a window in Firefox for me.
Or do distribution provides qtwebkit even when deprecated by their Qt
versions?
