Rollup merge of #71219 - JOE1994:patch-4, r=Mark-Simulacrum

Minor fixes to doc comments of 'VecDeque'

1. Changed descriptions of `fn get` & `fn get_mut`.
  Since both of these functions are returning references, and not the owned value, I thought the doc comments could be fixed to be consistent with doc comments of `fn front` & `fn front_mut`.

2. Other changes are minor fixes or additions for clarification.

Thank you for taking a look :)
