Auto merge of #11744 - matthri:get-first-deque-fix, r=Jarcho
Fix get_first false negative for VecDeque

fixes #11695

Also run the lint on `VecDeque` and suggest using `.front()` instead of `.get(0)` when trying to access the first element.

PS: At first I implemented the VecDeque Lint in a separate `if_chain` (see the previous commit).
Let me know if thats the preferred way, then I will remove the refactoring into one block.

changelog: [`get_first`]: fix false negative: Also lint `VecDeque` and suggest using `front()`
