bash: update to 5.1.16

[markusboehme]

Issue number:

#1613

Description of changes:

This updates the bash of the host, included in the -dev variants only, to version 5.1.16. The bash used now matches the version in the admin container used by sheltie.

Testing done:

• I built several variants multiple times and for both aarch64 and x86_64 (cross-compiled). I did not encounter the issue in Update bash to 5.1 #1613.
• Booted the metal-dev variant in QEMU and verified the bash version being used:

bash-5.1# echo ${BASH_VERSION}
5.1.16(1)-release
bash-5.1# bash --version
GNU bash, version 5.1.16(1)-release (aarch64-bottlerocket-linux-gnu)

Indeed, an artifact from a freshly setup developer box. Thanks to you and @jpculp for noticing!

I updated the PR with proper author information.
