packages missing in github mirror

[Jan Palus]

It appears that some packages are not mirrored to github.

Completely missing or tree empty (some of them missing due to notorious
dns issues):

bidilink
bos
bosh
confdir
dcaenc
distrobuilder
gnome-desktop-testing
gnome-voice
libnetfilter_cthelper
libnotifymm
mc-stan
ocaml-async
ocaml-cstruct
osgAL
osgcal
oslec
perl-HTML-TagParser
perl-Module-Path
python3-idna
python-flask
python-flask-wtf
python-manuel
python-markdown
python-PySide
python-sqlalchemy
python-werkzeug
python-wtforms
restic
sdr
unicode-emoji
vim-plugin-dbgp
yt-dlp

Since github has case insensitive repo names, some repos are not
mirrored:

GLE (github) + gle: different packages
GLM (github) + glm: different packages
katalog (github) + Katalog: different packages
libCSS (github) + libcss: different packages
par (github) + Par: different packages
