bash: upgrade to bash-preexec 0.6.0

https://github.com/rcaloras/bash-preexec/releases/tag/0.6.0

This is a small update for us because we've been using a patched version
of this script in Ghostty for some time, and the 0.6.0 release includes
most of the local changes we made as part of maintaining and improving
our bash shell integration.

- https://github.com/rcaloras/bash-preexec/pull/167
- https://github.com/rcaloras/bash-preexec/pull/170

We continue to maintain one local HISTCONTROL-related modification
(#2478). There are a few upstream conversations related to HISTCONTROL
that might eliminate the need for this local patch, so we may revisit
that in the future.
