[BUG] debian packages: bash completion script is installed to wrong place

[dseomn]

Description
salt-common from https://repo.saltproject.io/salt/py3/debian/12/amd64/latest includes /usr/share/bash-completions/completions/salt-common.bash/salt.bash, which doesn't seem to enable bash completion. From a glance at other bash completion scripts on my system, I think it should probably go in /usr/share/bash-completion/completions (no s in bash-completion) instead, and it looks like the filenames are based on the command names. So maybe it should be installed as /usr/share/bash-completion/completions/salt with symlinks salt-key, salt-call, and salt-cp pointing at that?

Setup
(Please provide relevant configs and/or SLS files (be sure to remove sensitive info. There is no general set-up of Salt.)

Please be as specific as possible and give set-up details.

• on-prem machine
• VM (Virtualbox, KVM, etc. please specify)
• VM running on a cloud service, please be explicit and add details
• container (Kubernetes, Docker, containerd, etc. please specify)
• or a combination, please be explicit
• jails if it is FreeBSD
• classic packaging
• onedir packaging
• used bootstrap to install

Steps to Reproduce the behavior

1. Install salt-common from Salt's Debian repos.
2. Use bash.
3. Try to use any of the tab completions in /usr/share/bash-completions/completions/salt-common.bash/salt.bash

Expected behavior
The tab completions in that file should work.
