TEST: bash 5.2.15-1

[Corinna Vinschen]

The following packages have been uploaded to the Cygwin distribution:

* bash-5.2.15-1
* bash-devel-5.2.15-1

This is a long overdue update of the bash shell.  Given the big
step in the version, this is a TEST release for now.  Please give
it a try.

This release is based on the Fedora Linux 37 bash release with
most patches from Fedora used for the Cygwin release, too.

This includes noticably:

- A bash-devel package
- real exeutables 

bash_DESCRIPTION="Bash is an sh-compatible shell that incorporates useful features
from the Korn shell (ksh) and C shell (csh).  It is intended to conform to the
IEEE POSIX P1003.2/ISO 9945.2 Shell and Tools standard.  It offers functional
improvements over sh for both programming and interactive use. In addition,
most sh scripts can be run by Bash without modification."
