[Enhancement]: Support core24

[jpm-canonical]

What changes would you like?

Trying to build a snap using core24 as base fails. The error is provided below. It looks like the docker container used for this action is not using a recent version of snapcraft that understand/knows about core24.

Any extra information?

Run diddlesnaps/snapcraft-multiarch-action@v1
  with:
    architecture: arm64
    path: .
    use-podman: false
    build-info: true
    snapcraft-channel: stable
  env:
    ARTIFACT_AMD64: tf-label-image_6_amd64
    ARTIFACT_ARM64: tf-label-image_6_arm64

Error: Your build requires a base that this tool does not support (core[2](https://github.com/jpm-canonical/tf-label-image-snap/actions/runs/9809019475/job/27086167104#step:4:2)4). 'base' or 'build-base' in your 'snapcraft.yaml' must be one of 'core', 'core18' or 'core20'.

Edit: #26 seems to solve this
