feat: doc-deploy-changelog update main branch option

[klmcadams]

Updates the changelog file and deletes the towncrier fragments on the main branch directly. This is mainly to fix these issues in the pre-commit hooks repo when doing releases: 203, 171

use-main-branch: true

• Skips creating the PR into main with the deleted towncrier fragments & updated changelog file
• Successful run after changelog is updated & fragment files are removed from main

default (update-release-branch is true and use-main-branch is false)

• release/x.y branch doesn't exist

  • Creates temporary branch to update changelog & remove towncrier fragment files
  • Successful run after changelog update & removed towncrier files
  • PR into main

• release/x.y branch exists

  • Checks out release/x.y branch to update changelog & remove towncrier fragment files
  • Successful run after changelog update & removed towncrier files
  • PR into main

both update-release-branch and update-main-branch are false

• Creates temporary branch to update changelog & remove towncrier fragment files
• Successful run after changelog update & removed towncrier files
• PR into main

both update-release-branch and update-main-branch are true (It will update the main branch)

• Skips creating the PR into main with the deleted towncrier fragments & updated changelog file
• Successful run after changelog is updated & fragment files are removed from main
