ci: 👷 Add permissions for pull requests

Updated CI configuration files to include permissions for pull requests. This change allows the CI to write to pull requests, enhancing the automation capabilities for the main-community branch.

• Added 'permissions' section to both update-docs-on-main.yml and update-size-on-main.yml.
• Ensures that the CI can manage pull requests effectively.
