dev: rename default git branch

[flavorjones]

Github has introduced support for alternative default branch names. However, Github's current guidance is to wait until they've updated their product to better handle renaming active repositories. One example of a current functional gap is that any pull requests that are based off master will be automatically closed if the branch is renamed.

Once Github has shipped their updates, then the maintainers will rename the master branch and any tooling (e.g. CI, webhooks) that needs to be updated.

Please watch this issue if you'd like to receive updates.
