Use a table to display changelog data

[DrewAPicture]

Changelog information is by nature tabular data, so we should probably be displaying it as such instead of as an un-ordered list. This change also makes the structure more predictable and improves readability and focusability for screen reader and keyboard users.

And it's looks nice too :-)

Note for the attached patch: Ended up needing to use a <caption> tag for the table to ensure a11y compliance instead of adding an id attribute to the <h3> – it was messing with the ToC's ability to render the section correctly.

+💯 for using a table.

php.net sorts the changelog from newest to oldest. Not sure if we should do the same.

+1 newest to oldest. As a developer I'm usually looking at a changelog because I want to know what changed in the most recent version.

I'm -1 on reversing the order. It's worth noting that our docs standard dictates oldest-to-newest in DocBlocks and they're therefore stored in that order when parsing. Doing an array_reverse() is trivial, but I'd kind of like to keep it consistently ordered in both places.

See #1819. See #1820.
