Rollup merge of #78620 - gabhijit:bitops_doc_fix, r=m-ou-se

Trivial fixes to bitwise operator documentation

Added fixes to documentation of `BitAnd`, `BitOr`, `BitXor` and
`BitAndAssign`, where the documentation for implementation on
`Vector<bool>` was using logical operators in place of the bitwise
operators.
