chore: fix edge build release artifact filenames (#5449)

#5440 accidentally changed the release asset filenames in our edge release: https://github.com/garden-io/garden/releases/tag/edge-bonsai

They used to look like this:
`garden-edge-bonsai-alpine-amd64.tar.gz` and now look like this: `garden-0.13.20-edge-bonsai-2779705b6-alpine-amd64.tar.gz`

This commit reverts to the old filenames so self-update downloads the correct artifacts.
