Invalid multi platforms docker image

[TonyRL]

Describe the bug
Only one platform of docker image is pushed.

To Reproduce
Steps to reproduce the behavior:

1. Go to https://hub.docker.com/r/riccoxie/meilisearch-ui/tags
2. See error

Expected behavior
Each image should have multi arch support.

Screenshots
N/A.

Environments (please complete the following information):

• OS: N/A
• Browser N/A
• Version N/A

Additional context
You can refer to docker/build-push-action#846 for more details. According to Multi-platform image with GitHub Actions, if you really want to build multi platform image which utilises job matrix you need to upload all the images as artifacts and then download them and merge them before pushing to Docker Hub.
Otherwise, the old GitHub actions is good to go.
