AWS Organizations increases quotas for tag policies

Tag policies help you govern tag consistency across resources in your organization’s accounts. For example, with tag policies, you can define rules on tag keys, including how they should be capitalized and their allowed values. With this release, the maximum size of a tag policy document has been increased from 2.5k to 10k characters for both new and existing tag policies. The number of allowed policies has also been increased from 5 to 10.
