In PLANET-4148 we are asking to disable Gutenberg's native "Gallery" block, since these features are now allowed with the P4 Gallery block.

Once Gutenberg is stable in all p4 sites, however, we should perform a review of this blocks and see how well it performs the same tasks of the P4 Gallery block, rendering the same way etc.

The idea is to retire the P4 Gallery Block and just leverage the Gutenberg native one, with (if needed) CSS adjustments, GPI Media Library integration etc etc.

Review should include:

• Potential CSS adjustments
• Potential heading and description adjustments
• Functionality matrix review P4 Media Block VS Native blocks
• Recommendations for migration of existing P4 gallery Blocks to Gutenberg gallery
• Recommendation for adoption in Campaigns
• Dev tasks to implement any of the above
