About page for 5.9, first pass

[ryelle]

Getting a PR up for the About page. I thought the copy was stable as of 12/20, so that's what this uses, but there's still discussion ongoing today so I'll swing back through and update it once that's finalized. (In the future, the copy should be final before/in tandem with design, ideally before beta).

I still need to drop in the other pages' header assets, and figure out what to do about column sizing. In this PR, I've tweaked the size of the "wider 2-column" layout to be two-fifths/three-fifths, which fits the (older?) copy & images better. Whatever is decided about the sizing, I can make that change (cc @critterverse).

Desktop [1250px wide]

Tablet [750px wide]

Phone [480px wide]

Now with updated headers, including the shorter header text on Freedoms.

Looks great, thank you for making the headings a bit smaller 👍

Updated "Navigation block" section:

Updated "Paintbox" sections:

Updated developer note — I changed the theme.json section to "Introducing Block Themes" (should that be sentence case?) and copied/tweaked some content from the dev note for the section itself.

Looks great! 👍 Found a small regression on the freedoms page. The PR removes the gap between the rows.

And on "tablet" the first column isn't aligned correctly.

"refactor" is a verb. The corresponding noun would be "refactoring".
Therefore "a near-complete refactor" should be "a near-complete refactoring".

The PR removes the gap between the rows.

Thanks for reporting that — since that's a CSS issue, we can work on that post-RC1.

@ryelle LGTM! I think it's ready for commit 👍
