Add org.opencontainers.image.source to Dockerfiles (#9211)
### Purpose

The OCI image spec specifies well-defined
[annotations](https://github.com/opencontainers/image-spec/blob/main/annotations.md)
that can be added to images.
Theses annotations can then be used by other tools to gather more
information of an image.

This PR adds the `org.opencontainers.image.source` to allow tools such
as [renovate](https://github.com/renovatebot/renovate) to find the
release notes of a give version.

~~I've only done this change for `Dockerfile`. Should I also add the
label to the other dockerfiles?~~
I've now added the source annotations to all `Dockerfile`s & action
workflows.

### Testing

None, change was done by following the [renovate
documentation](https://docs.renovatebot.com/modules/datasource/docker/).

# Maybe build Syncthing. This is a bit ugly as we can't make an entire
# section of the Dockerfile conditional, so we end up always pulling the
# golang image as builder. Then we check if the executable we need already
# exists (pre-built) otherwise we build it.
