Help/About: Left-align 6.2 about page subheading.

This changeset removes the `aligncenter` class from `h2` and `is-subheading` items in the WordPress 6.2 About Page, for more consistent alignment. Also, future minor releases will add more left-aligned paragraphs under the "Maintenance Releases" section.

Props shagors, sabernhardt, mukesh27, amin7, costdev, pavanpatil1, audrasjb.
Merges [55716] to the 6.2 branch.
Fixes #57387.
