Renaming master branch to main

[geekygirldawn]

Hi everyone,

It would be great if we could make the change to rename the GrimoireLab default branch from master to main. I know this is a disruptive change, since it means that every developer needs to update their fork of every repo, and if any automation or scripts make assumptions about the branch name, those might need to be updated, too.

I'm bringing this up now because this might be something that is best done over the end of the year holidays when things might be slower?

It looks like almost all of the branches are still using master (except for the gitee ones):

• chaoss grimoirelab master
• chaoss grimoirelab-bestiary master
• chaoss grimoirelab-cereslib master
• chaoss grimoirelab-elk master
• chaoss grimoirelab-elk-gitee main
• chaoss grimoirelab-github-actions master
• chaoss grimoirelab-graal master
• chaoss grimoirelab-hatstall master
• chaoss grimoirelab-kidash master
• chaoss grimoirelab-kingarthur master
• chaoss grimoirelab-manuscripts master
• chaoss grimoirelab-perceval master
• chaoss grimoirelab-perceval-gitee main
• chaoss grimoirelab-perceval-mozilla master
• chaoss grimoirelab-perceval-opnfv master
• chaoss grimoirelab-perceval-puppet master
• chaoss grimoirelab-perceval-weblate master
• chaoss grimoirelab-sigils master
• chaoss grimoirelab-sirmordred master
• chaoss grimoirelab-sortinghat master
• chaoss grimoirelab-toolkit master
• chaoss grimoirelab-tutorial master

This isn't super urgent, but it's something we should probably do eventually.
