Add 2024 Annual Rust survey announcement blog post

[Kobzol]

Opening as a draft, it is not complete yet, although most of the stuff should be there. 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.

I suggest adding an intro to this section this year. Something like:

"The State of Rust survey not only gives us excellent insight into how many Rust users around the world are using and experiencing the language but also gives us insight into the makeup of our global community. This information gives us a sense of where the language is being used and where access gaps might exist for us to address over time. In this section of the survey recap, we'll summarize a few community metrics: country of residence, preferred language for technical communication, and which traditionally underrepresented or marginalized communities respondents consider themselves members of. We hope this information and our related analysis help further important discussions about how we can continue to prioritize global access and inclusivity in the Rust community."

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.
