You can use an alias and forget the special command.
Add this line to ~/.bashrc:

# Let gitk work on host display
alias gitk="DISPLAY=:0 gitk"

As .bashrc is the same for container and full VM, I won't add this 
configuration.
I'll add only a suggestion in the README.

I've tried lynx, but it's not working correctly.
It ends up with this link: 
https://codereview.appspot.com/get-access-token?port=8001
but does not go beyond this and I have to cancel with Ctrl+C.

If you want to give it a try:

sudo dnf install lynx

BTW, let me know if the password is working. I'm not sure I've uploaded 
the correct version..
If it doesn't, use this command as root:

 echo 'dev:lilypond'|chpasswd


Create ~/.lynxrc and add these lines:

ACCEPT_ALL_COOKIES=TRUE
PERSISTENT_COOKIES=TRUE
COOKIE_FILE=/home/dev/.lynx_cookies
COOKIE_SAVE_FILE=/home/dev/.lynx_cookies
FORCE_SSL_COOKIES_SECURE=FALSE
AUTO_SESSION=TRUE
SESSION_FILE=/home/dev/.lynx_session
