[Bug] Parse error caused by FROM instruction with digest

[Mogyuchi]

Describe the bug
When the expression FROM <image>@digest is included, a parse error occurs.
It also gives an error when I use FROM <image>:tag@digest.

dprint-plugin-dockerfile version: 0.3.0

Input Code

FROM ghcr.io/jqlang/jq@sha256:12f998e5a6f3f6916f744ba6f01549f156f624b42f7564e67ec6dd4733973146 as fetch-jq

Expected Output

FROM ghcr.io/jqlang/jq@sha256:12f998e5a6f3f6916f744ba6f01549f156f624b42f7564e67ec6dd4733973146 AS fetch-jq

Actual Output

$ dprint check Dockerfile

It looks like there are a couple of PRs (15 and 31) that try to fix this, but there hasn't been any response in a while. I'm wondering if it'll be possible for this plugin to use a patched fork while upstream gets to any of those PRs?

Fixed in #20, dprint-plugin-dockerfile 0.3.3
