needed for DELTACAST, otherwise manpage generation fails with:

which tries to run bin/uv with --fullhelp.
(this fails only if run within the script data/make_man.sh, not when run directly)
the message: `Error: No such keg: /opt/homebrew/Cellar/asciidoctor`
is now print on stderr, which disturbs GitHub CI (complains about it in
action summary annotations; just a warning).
`
The GitHub actions now complain if trying to install a formula, that is
already installed, eg:
```
run macOS (macos-14)
pkg-config 0.29.2_3 is already installed and up-to-date. To reinstall 0.29.2_3, run: brew reinstall pkg-config
```
As a workaround, install just the formulas, that are not already
installed.
It is not needed to split the string like this:
```
a="potentially long string on"\
"multiple lines"
```
but it is better rather to put the '\' inside the string:
```
a="potentially long string on\
multiple lines"
```
Download installers if not present. They usually are, because are cached
by the workflow. However, this change is mainly to allow the installation
not by CI but on some local computer for debugging purposes by C&P.
Using `cmake --build . --parallel` actually doesn't limit the number
of processes because it just passes the number (here none) to make,
resulting in `make -j`.
This is a possible explanations of macOS runner freezes, as eg. here:
<https://github.com/MartinPulec/UltraGrid/actions/runs/7641831068>
(last relevant message in log is `[100%] Built target joysticks`).
Following to previous commit, we can build with Qt 6 (even thought that
a workaround is neeeded).
qt package (version 6) is installed anyways as a dependency of opencv
Install vulkan headers prior to updating homebrew tree.
the version 1.3.264 seem to be temporarily broken (see [1]), producing
error:

the version 4.1.7 in GH runner is unsolicitedly producing
relocatable install names as it would with (in recent HB version)
HOMEBREW_RELOCATABLE_INSTALL_NAMES=1
see failed run:
<https://github.com/CESNET/UltraGrid/actions/runs/6147222102/job/16745596096>
The relocatable install names like:
$ otool -L /usr/local/opt/qt/lib/QtGui.framework/QtGui | grep png
@loader_path/../../../../../../../opt/libpng/lib/libpng16.16.dylib
Makes significant problems to macdylibbundler (it doesn't copy the library
to the bundle at all neither chantes the name).
\+ reinstall freetype (see failed build
<https://github.com/MartinPulec/UltraGrid/actions/runs/6185513000/job/16791263362>)
fixes failed run

From some point, it seems that Qt6 (Homebrew port _qt_) is already
installed but it doesn't bundle successfully. So enforce using Qt5
(previous symlink command didn't replace the `/usr/local/opt/qt` symlink
if already present).
\+ copy the link instead of linking it to prevent:
Error: /usr/local/opt/qt@5 is not a valid keg
Copy sounfont to known path for macOS and Windows CI builds (in Linux,
this is already handled with a environment var SDL_SOUNDFONTS). And also
use that location if there is any soundfont.
Use of OpenSSL required a bit tweaking on mac. Also the new library is
faster and and smaller, which makes is better suitable for UG.
Note: other platforms are not compatible with wolfSSL yet - U18.04 does
contain old/incompatible version. MSYS2 doesn't build wolfSSL.
