Replace italics with alternate styling in deck / context

[deviantintegral]

Describe the bug
Look at https://architecture.lullabot.com/adr/20211207-ddev-locals/

In my view, a paragraph in this font in italics is hard to read. Given how important context is to ADRs, I would like us to improve the readability of this.

To Reproduce

Browse an ADR site like at https://architecture.lullabot.com/adr/20211207-ddev-locals/

Additional context

I think something like a blockquote style, minus the existing italics would be better, but it's not perfect. But, I'm not a designer so I'm open to ideas!

I am OK with the change. For context, the style was grabbed from the current Lullabot.com site.

Huh, TIL'ed! Perhaps this isn't an issue for most people. I'm happy to leave this open for a bit for further feedback.
