ci: 👷 Update permissions for CI jobs

Updated the permissions in the CI configuration files to allow write access to contents. This change is necessary to enable the CI jobs to function correctly with the required permissions for pull requests and content management.

• Added write permission for contents in both update-docs-on-main.yml and update-size-on-main.yml.
