[FLINK-39796] Fix snapshot bake by pinning bake-action to local source
(#261)
bake-action v7 changed the default of an unset `source` input: it now
falls back to the workflow's git context and bakes it as a remote ref,
so buildx fetches docker-bake.hcl and the build context from the
triggering commit on master.
That breaks the snapshot workflow for two reasons:
1. master's docker-bake.hcl lacks the `target "docker-metadata-action" {}`
stub that every dev-* branch defines, so `inherits` fails with
`failed to find target docker-metadata-action`.
2. the snapshot Dockerfile is generated at runtime by add-custom.sh into
the local working tree and is not committed, so a remote bake context
could not find it anyway.
Setting `source: .` restores the pre-v7 behavior of baking the local
working tree (the checked-out dev-* branch), which has both the generated
Dockerfile and the docker-metadata-action stub.
