OCI Metadata Labels Broken When Using Hyperlinks

[mu88]

Describe the bug

Hey @baronfel,

Please refer to this discussion: when using the .NET SDK Container Building Tools and using hyperlinks, this breaks the OCI metadata labels.

For example, please see this image manifest of a container image built using the .NET SDK Container Building Tools:

{
  // remainder left out for brevity
  "labels": {
    "org.opencontainers.image.source": "https",
    "com.docker.extension.changelog": "https",
    "org.opencontainers.image.url": "https",
    "org.opencontainers.image.licenses": "https",
    "org.opencontainers.image.documentation": "https",
    "com.docker.extension.publisher-url": "https",
  }
}

But I properly ensured via some MSBuild output on GitHub Actions that the necessary properties are present:

GITHUB_REPOSITORY_OWNER: 'mu88'
GITHUB_SERVER_URL: 'https://github.com'
GITHUB_REPOSITORY: 'mu88/RaspiFanController'

To Reproduce

1. Create a new .NET project.
2. Publish a multi-arch Docker image via dotnet publish /t:PublishContainer /p:RuntimeIdentifiers=linux-x64;linux-arm64 /p:ContainerDocumentationUrl=https://dot.net.
3. Inspect the OCI metadata labels of the built image - you will see that the hyperlink is broken and only contains https.

Exceptions (if any)

No exceptions

I think that this is the culprit: when calling "org.opencontainers.image.documentation:https://dot.net".Split(':')[1], this will only return https, because due to the trailing colon, the remainder will be put into the split array's third bucket / [2].
Maybe the solution could be using .Split(':', 2)[1] instead of .Split(':')[1], hereby putting everything after the very first colon (i.e. the hyperlink) into the second bucket / [1].
