Change the default branch name

[rtyler]

Most branches created in recent history use main to denote the primary branch. This value is used in the snippet generator, so important to have correct IMHO

Thanks for the pull request @rtyler. Unfortunately, many more changes are needed before we can adjust the default branch name in the Pipeline step to use main instead of master. If you're interested in doing those changes, they would include:

• Update tests to adapt to the new default branch name
• Update documentation to describe the new default branch name
• Perform compatibility tests to confirm the new default branch name does not break existing users that are still using master as the primary branch name
