Following up on the 2.2.2 (and 2.2.3) release from last week, this 2.2.4 milestone addresses a regression in the handling of hero images on optimized AMP pages, specifically when the data-hero attribute had been manually-supplied by a theme/plugin author.

• Restrict collection of attributes allowed on noscript fallback elements. (#7036)
• Upgrade amp-toolbox-php to 0.11.1 to harden hero image optimization when noscript > img fallbacks are present (#7039, https://github.com/ampproject/amp-toolbox-php/pull/516)
