Add 2024 Annual Rust survey announcement blog post

[Kobzol]

I took the blog post from last year and rewrote it for this year's results, which some changes (adding a "Learning Rust" section, and removing so many mentions of percentages).

Accompanying surveys repo PR: rust-lang/surveys#327

for stuff written in english afaik it's conventional for most graphs to have earlier years on the left and later years on the right (so time progresses in the same direction as writing text), the graphs here have that reversed which can be confusing

Great point! I changed the order.

thanks @graciegregory for the addition. I believe this sentence

{go into reported racial/ethnic minority and identity metrics and analyze comparatively to 2023}

looks like a TODO item so I'll remove it from the blog post.

@Kobzol I think we're fine here and ready to merge. Feel free to have a final look, in case I have missed anything

(I didn't force push on your branch to make it easier a revert of my commit. just in case.)

I made a few tiny changes, but otherwise I'm fine with the current version. I will send it to Zulip and we'll publish it on Thursday.
