[SSHDConfig] Move filepath from metadata to properties

[tgauth]

PR Summary

• move filepath from metadata to properties for sshdconfig resources
• bump sshdconfig resource versions

PR Context

• fix SSHDConfig Resource: filepath should be in properties instead of metadata #1570

[Copilot]

Pull request overview

This PR updates the sshdconfig DSC resource to treat the target sshd_config path as an input property (_filepath) rather than an item under _metadata, aligning configuration shape with how the path affects resource behavior (per #1570).

Changes:

• Replace _metadata.filepath with _filepath across the sshdconfig resource schemas, Rust input parsing, and most Pester tests.
• Update canonical-property handling to recognize _filepath as a first-class canonical property.
• Adjust get/set code paths to read/write and echo _filepath rather than _metadata.

We want to only use leading underscore properties for canonical properties, so in this case, it should just be filepath. I think with a concern about name collision with a future SSHD keyword, we should discuss in the WG whether we elevate to a canonical property _filepath particularly if such a scenario would affect many different resources which might be the case.
