Bento: Fix unrecognized DOM attributes

[caroqliu]

Updates:

• removed allowTransparency due to Remove allow transparency facebook/react#10823
• lowercased allowfullscreen
• removed expanded from final render state of BentoAccordionSection
• removed keyboardSelectMode from final render state of BentoSelector
• removed thumbnailSrc from final render state of slide children of BentoBaseCarousel
• renamed given ariaLabel prop to aria-label on BentoVideo

In a follow up PR, the expanded prop should be removed from final render state of BentoAccordionSection, but it is not done so in this PR because it is more involved and has implications on the AMP mode shims.

The following changes specifically were not made as the left hand side is preferred for preact and the right hand is preferred for react, therefore we need our build to account for these instead of changes to the sourcecode:

• allowfullscreen -> allowFullScreen
• class -> className
• datetime -> dateTime
• frameborder -> frameBorder
• srcset -> srcSet
• svg kebab-case -> svg camel case

Partial for #35553
