Rollup merge of rust-lang#123595 - balaganesh102004:master, r=joboet

Documentation fix

Changed "It must not be an identical residual when interconversion is involved" to "The residual is not mandated to be identical when interconversion is involved." as the previous parenthetical appears to state that the residual is not permitted to be identical when interconversion is involved. However the intention of the original wording was to convey that the residual is not required to be identical when interconversion is involved, which makes more sense contextually.
