Fix [Bug #19632]: Disable external iterator for frozen enumerator (#7791)
* Fix [Bug #19632]: Disable external iterator for frozen enumerator
Currently, methods to manipulate an external iterator like `#next`
and `#feed` can be called even if a receiver of an enumerator is
frozen. However, these methods change the state of an external
iterator in an enumerator. Therefore, it seems a BUG to me, and
these methods should raise FrozenError if the receiver is frozen.
This fixed the following methods to raise FrozenError if the receiver is
frozen.
- `Enumerator#next`
- `Enumerator#next_values`
- `Enumerator#peek`
- `Enumerator#peek_values`
- `Enumerator#feed`
- `Enumerator#rewind`
* Fix a typo in the document
Thanks @Maumagnaguagno.
