Errors when running bootstrap on alpine

[marccardinal]

Description of Issue/Question

Bootstrap failure on alpine:3:18 with v3006.3.

Steps to Reproduce Issue

1. Launch a new alpine container using:

docker run -it alpine:3.18 sh

2. At the container's prompt, run:

apk --no-cache add curl
curl -L https://bootstrap.saltproject.io | sh -s -- -M -N git v3006.3

The above results in:

Successfully installed salt-3006.3
WARNING: Running pip as the 'root' user can result in broken permissions and conflicting behaviour with the system package manager. It is recommended to use a virtual environment instead: https://pip.pypa.io/warnings/venv

Installed Salt Version: 3006.3

Running the same command targeting the v3005.3 tag yields the same results given that the reference to the underlying salt repo is done without tag and it would use whatever the state of master is at the time.

This stems from this section of the bootstrap file: https://github.com/saltstack/salt-bootstrap/blob/develop/bootstrap-salt.sh#L6047-L6048 and indeed if we look at the state of the salt repo between the 3005.x and 3006.x branches we see that the alpine folder disappeared:

https://github.com/saltstack/salt/tree/3005.x/pkg
https://github.com/saltstack/salt/tree/3006.x/pkg

Is the drop of alpine support by design or this is an unexpected regression?

Thanks!
