Rename master branch to main

[steven-sheehy]

Problem
In honor of Juneteenth, we want to rename our master branch to main as much of the industry already has.

Solution

• Change any references to master in the codebase to main
• Rename master branch to main in Github settings
• Adjust local git settings

git branch -m master main
git fetch origin
git branch -u origin/main main
