docs: use `main` instead of `master` when referring to Git branch

[HonkingGoose]

New feature motivation

The semantic-release docs use master when referring to a Git branch. I think this should be changed (eventually) to main seeing as GitHub and GitLab now default to main for new repositories.

I think issue #1581 needs to be resolved first, before somebody can change the references in the docs?

New feature description

Replace master with main when referring to a Git branch in the semantic-release documentation.

If needed you can add a short explanation stating that master is the old term and the many Git hosting providers settled on using main instead.

New feature implementation

From what I understand, there's more to it than this because if you don't set up any branches, semantic-release assumes master.
I think it's time main were assumed in preference to master and if both exist, then semantic release would require branches config.

Once we finish the ESM transition, working on supporting main out-of-the-box will be a high priority for me. I'd wait until then before adjusting the docs

Is there anyway to configure semantic-release to work with main at the moment? I've added main to release -> branches config but it errors with ERELEASEBRANCHES
