`try_skip_while` and `try_take_while` have inaccurate doc comments (errors are passed through)

[ttttcrngyblflpp]

The documentation of try_take_while states:

This function is similar to StreamExt::take_while but exits early if an error occurs.

The actual behavior is that errors are passed through. It seems like the wording should be changed to match, e.g. try_filter. try_skip_while has the same problem.

Alternatively, perhaps all TryStreamExt combinators which return a TryStream should actually not yield more than one error (this is possible, e.g. if selecting between two TryStreams).
