[Contrib] Default branch is renamed to 'main', steps for you

Following the directions on this page, which I found easy to perform ... https://docs.github.com/en/github/administering-a-repository/renaming-a-b... ... I renamed our default branches to 'main'. https://github.com/theopensourceway/guidebook https://github.com/theopensourceway/theopensourceway_old_website https://github.com/theopensourceway/theproject If you have a clone of one of our repos[1] you need to do the following steps, as described in the docs above. cd /path/to/local/clone git branch -m master main git fetch origin git branch -u origin/main main If it complains after the first step that 'main' already exists, proceed forward and it should finish with" Branch 'main' set up to track remote branch 'main' from 'origin'. This concludes issue #106. https://github.com/theopensourceway/guidebook/issues/106 I'm relieved this is done. I've been putting work into https://inclusivenaming.org and hadn't come back to clean up our own house. Well, every little turn of the wrench and sweep of the broom it is. Kind regards, - Karsten [1] A clone meaning, you have gone to the command line and run 'git clone url_from_github_for_cloning'. If yes, these are the three repos I changed and you will need to run the above commands for each repo: 'guidebook' 'theproject' 'theopensourceway_old_website' -- Karsten Wade [he/him/his]| Senior Community Architect | @quaid Red Hat Open Source Program Office (OSPO) : @redhatopen https://community.redhat.com | https://next.redhat.com | https://osci.io https://theopensourceway.org | https://github.com/theopensourceway/guide
