Change lazygit's branch name from master

**Topic**
Changing the lazygit repo away from master branch name to something else, such as the git and GitHub default of main

**Your thoughts**
Given that lazygit is surrounding git, I feel like having a precedent set here especially would be a good thing to consider. Especially with the master/slave connotation that some can feel, which can for example add up throughout the industry as death by a thousand cuts
