Rollup merge of #149232 - madsmtm:vec-doc-aliases, r=Noratrieb

Add doc aliases "vector" and "list" to `Vec`

- "vector" is what "vec" is short form for.
- "list" is a common name for this concept in a lot of other languages (`ArrayList` in Java, `list` in Python, `List` in C#). C++ uses the term for a linked list (`std::list`), so maybe this is contentious?

I believe that this falls under [the doc alias policy](https://std-dev-guide.rust-lang.org/policy/doc-alias.html), and I think it's plausible that a newcomer would search for either of these terms, and expect to find `Vec`.
