+  A semicolon-separated list of names of types that
+  will be excluded from const-correctness checking.
+  Regular expressions are accepted, e.g. `[Rr]ef(erence)?$` matches every type
+  with suffix `Ref`, `ref`, `Reference` and `reference`.
+  If a name in the list contains the sequence `::` it is matched against
+  the qualified typename (i.e. `namespace::Type`), otherwise it is matched

I must note that files `for-range-copy.rst`, `unnecessary-copy-initialization.rst`, `unnecessary-value-param.rst` have the same errors in description of AllowedTypes option.
Should I also make these corrections in https://github.com/llvm/llvm-project/pull/122957?
