Docs for all overloads of ToFrozenDictionary should contain the same remark.

### Type of issue

Missing information

### Description

Look at the remarks section [of this `ToFrozenDictionary()` overload](https://learn.microsoft.com/en-us/dotnet/api/system.collections.frozen.frozendictionary.tofrozendictionary?view=net-9.0#system-collections-frozen-frozendictionary-tofrozendictionary-2(system-collections-generic-ienumerable((system-collections-generic-keyvaluepair((-0-1))))-system-collections-generic-iequalitycomparer((-0)))).

> If the same key appears multiple times in the input, the last one in the sequence takes precedence. This differs from [ToDictionary](https://learn.microsoft.com/en-us/dotnet/api/system.linq.enumerable.todictionary?view=net-9.0), where duplicate keys result in an exception.

It's absent in other overloads.
