Add initial 1.52.0 post

This cycle didn't have a lot of notable stabilizations or changes in the language or standard library so I ended up keeping things pretty concise. If someone has particular things they'd like to highlight that seems positive - though I'd rather not devote too much time to something minor - we can definitely iterate further.

Ok, made some adjustments - I feel like it's missing some structure (maybe headings or so) but then the sections get really small, not sure what to do about that. Maybe just some better flow would work.

Wow, I didn't know the cargo check/cargo clippy bug was finally fixed. That's a huge UX improvements for people not using an IDE, and it deserves to be the first thing mentioned in the post IMO (with its own section).

That leaves loop {} as the only minor change, and I guess we could either remove it or add it as its own section below the Clippy change. I'm not familiar enough with the loop {} change to know whether it's important for it to be featured in the post.

Heh, I don't use clippy ~at all myself so it's not really that big a deal in my eyes, but I can uplift it a bit into its own section. I think doing that will make it reasonable to drop the loop {} thing, it's not really a big deal, mostly there as a "well nothing else".

Oh yeah, this is a pretty big thing for Clippy. This bug was around for years and it is an example of successful collaboration between the cargo and the Clippy team to finally get this fixed.

Ok, I changed this to focus on just Clippy -- I am open to suggestions further though.

Clippy part LGTM

Looks great! Thanks Mark for writing the post this cycle!

That was supposed to be an approval 😅
