Re-add Maintenance and Security Releases changelog to the About page

[SergeyBiryukov]

Background: #47708

With the overhauled About page design in 5.3, we need to make sure there is a place and appropriate design for the Maintenance and Security Releases changelog, same as in previous minor releases.

See the screenshot of the changelog in 5.2.4 for reference.

After 48945.diff

[SergeyBiryukov]

@audrasjb Ah, I got a similar result with 48945.2.diff​ / 48945.2.PNG​ :)

It also includes a padding for the section, which appears to be missing in 48945.diff​.

[melchoyce]

Approach looks good to me 👍

I started with a padding bottom but I replaced it with a <hr /> tag since it's the approach adopted for the other blocks :-)
Also, it avoids us to add new css rule ;)

Thanks for your feedback Mel!

Ah, I missed that <div class="column"> already has the required padding. Should be good to go, then :)

[audrasjb]

Ah sorry I confused between padding and margin :D

But yes, indeed, I think we are good to go (and we have proper validation from the design team :)

Props audrasjb, melchoyce.

Hey, I just realized @ryelle had some docs for this: ​https://gist.github.com/ryelle/91ef6cd84a197b6af880dc055be21cc9 Does this match?

Thanks for the link! Yes, this seems to match what was done in [46892] for 5.3 and [47702], [47773] for 5.4.

The only difference is that the .point-releases class is no longer used, it's only used in legacy About styles.
