Rename default branch

[dvdksn]

Proposed changes

This PR updates the name of the default branch (from master to main) in files of the docs repository.

In addition to this PR, three additional changes must take place:

• Update the ref name in the subject claim of the website_docs_docker_com Terraform module
• Rename the branch on GitHub
• Update the production branch name in Netlify

Only when the above changes are completed should this branch be merged. We should coordinate the changes as such that this PR is the first to get merged after the changes are made.

@crazy-max I think I caught all relevant occurrences of master here.

Thanks @dvdksn. I believe we should also update the workflows in GH Actions. For ex: https://github.com/docker/docs/blob/master/.github/workflows/build.yml

@dvdksn As discussed I will open a PR to update subject claim in terraform module to deploy to AWS. Also I think we have to update the prod branch on Netlify:

LGTM, let's wait for subject claim to be changed and branch being renamed before merging.

@crazy-max @dvdksn Wondering how the branch rename would affect the existing PRs that still point to the 'master' branch?

Will be changed automatically.
