wrong doc on Open5GS tutorial Dockerized VoLTE Setup

[gmaruzz]

probably totally independent from here, but tutorial in https://open5gs.org/open5gs/docs/tutorial/03-VoLTE-dockerized/ at step 2 (build base docker images) say:

cd ../kamailio_base
docker build --no-cache --force-rm -t open5gs_kamailio .

that is wrong, it must say:

cd ../ims_base
docker build --no-cache --force-rm -t docker_kamailio .

You are right. That needs correction. Please open a PR in open5gs repo. Thank you for pointing it out
