Revert "add color-backtrace crate (#10942)" (#11032)

The `color-backtrace` crate does not seem to either handle the terminal
modes well or operate in a way that the unwinding has not yet succeeded
to reach the backup disablement of the terminal raw mode in
`reedline::Reedline`'s `Drop` implementation.

This reverts commit d838871063.

Fixes #11029
