Update time component references from yoshuawuyts to microsoft registry

[Copilot]

Summary

This PR updates all documentation references to the time component to point to the official Microsoft-maintained component in the GitHub Container Registry.

Changes

All references to oci://ghcr.io/yoshuawuyts/time:latest have been replaced with oci://ghcr.io/microsoft/time-server-js:latest across the documentation:

• README.md: Updated the main getting started example and the load-component tool documentation
• docs/reference/cli.md: Updated CLI usage examples for loading components from OCI registries
• docs/installation.md: Updated the "Load your first component" verification step

Motivation

The component-registry.json file lists the Time Server component at oci://ghcr.io/microsoft/time-server-js:latest, but the documentation was still referencing an older external registry location. This misalignment could cause confusion for users following the getting started guide.

By updating these references, we ensure:

1. Users are directed to the officially maintained Microsoft component
2. Documentation is consistent with the component registry
3. Examples work with components that are actively maintained by the project

Testing

Verified that:

• All old references to yoshuawuyts/time have been removed from documentation
• All updated references point to the correct Microsoft component registry location
• Changes are documentation-only and do not affect code functionality

Original prompt

Modify this section from the README:

Please load the time component from oci://ghcr.io/yoshuawuyts/time:latest
Now that the time component is loaded, we can ask your agent to tell you the current time:

What is the current time?
