Is your feature request related to a problem? Please describe.

Historically, v1.x.y-1.0 v1.x-y or edge was designed to point alpine image.

but alpine image was already marked as deprecated.
See README.md.

There is no reason to provide alpine image anymore.

Describe the solution you'd like

In the future release, switch default image from alpine to debian and drop alpine support.

e.x.

• Keep alpine for v1.18 series
• Drop alpine for v1.19 series
  • v1.19.0-1.0, v1.19-1, edge just points debian image

Describe alternatives you've considered

• Keep alpine for v1.16 (LTS), v1.18 series
• Drop alpine for v1.19 series
  • Discontinue v1.19.0-1.0 v1.19-1, edge tagging
