Ill-formed package index emitted

[Dichloromethane]

When the following container is build, running apk info results in

ERROR: This apk-tools is too old to handle installed packages
ERROR: Unable to read database: v2 database format error
ERROR: Failed to open apk database: v2 database format error

archs:
  - aarch64

contents:
  repositories:
    - https://dl-cdn.alpinelinux.org/alpine/edge/main
    - https://dl-cdn.alpinelinux.org/alpine/edge/community
  keyring:
    - https://alpinelinux.org/keys/alpine-devel@lists.alpinelinux.org-6165ee59.rsa.pub
  packages:
    - alpine-base
    - eudev
    - eudev-openrc

Commands to reproduce:

apko build minimal.yaml test:latest minimal.tar
docker load < minimal.tar
docker run --rm test:latest-arm64 apk info

An LLM told me the error is because the i: field in the database is ill-formed (it shouldn't have the []), which seems correct, as the apk documentation says that "i: - install if (corresponds to install_if in PKGINFO, concatenated by spaces into a single line)" and does not mention [].

Seems like an beginner level fix and this package file need to be change "pkg/apk/apk/apkindex.go". Can I work on this?
