Is your feature request related to a problem? Please describe the problem.

I am trying to publish a site page after I update its content, but I must use Invoke-MgGraphRequest to do so.

Describe the solution you'd like.

Please add a cmdlet such as Publish-MgSitePage to handle this endpoint.

Additional context?
