3/ update update_version script to upload new versioned content/images to s3
Summary:
depends on D8558
- create versioned content /tmp/versioned_content/<version_value> and upload it to s3/versioned_content/<version_value>
- create versioned images /tmp/versioned_images/<value_value> and upload it to s3/versioned_images/<version_value>
- prettify versions and versioned_navigation json so git can better capture the changes (trying to avoid the merge conflict caused by master and release branch out of sync)
Test Plan: ran python update_version.py --version 0.11.foo locally
