Bug: Synced pattern wrappers are stripped.

What

Currently, when querying for synced patterns the patterns are stripped just like unsynced patterns.

This makes it impossible to query the pattern data - for example the attributes?.slug that could allow someone to target and "upgrade" the block with a frontend component.

To replicate:

1. Create a synced pattern on a post.

   

2. Query the post and note the inner blocks are there, but the pattern isnt.

   (The first 3 blocks are part of the pattern)
   

Additional Notes

• Assumedly the issue is with https://github.com/wpengine/wp-graphql-content-blocks/blob/e9354071642aa78368ec7adfbe8badc495e9931b/includes/Data/ContentBlocksResolver.php#L281 merging everything instead of populating inner blocks w. it.
• Partially-synced patterns also dont work but one step at a time.
