linux/amd64 image missing in ghcr

[tHeCh0s3n0n3]

It appears the docker actions using Matrix only push the last one's manifest. This leads to only linux/arm64 being available (and not linux/amd64)

Steps to reproduce:

1. Be on a linux/amd64 machine
2. Try to pull the image docker pull ghcr.io/damomurf/coredns-tailscale:v0.3.10 --platform linux/amd64

Expected Result:

Successful pulling of the image

Actual Result:

v0.3.10: Pulling from damomurf/coredns-tailscale
Digest: sha256:5e9af07c1fbe542bf70860735cc9a359ae81cc4e74a6397c45026c3f4623bf80
Status: Image is up to date for ghcr.io/damomurf/coredns-tailscale:v0.3.10
image with reference ghcr.io/damomurf/coredns-tailscale:v0.3.10 was found but does not match the specified platform: wanted linux/amd64, actual: linux/arm64
