Not able to publish a SharePoint page, so created page is stuck in "Checked out"

Expected behavior

Based on the API documentation here:
https://learn.microsoft.com/en-us/graph/api/sitepage-publish?view=graph-rest-1.0

I would expect this code to compile:

client.sites().bySiteId(ms.getSiteId()).pages()
	.byBaseSitePageId("0eb44212-1667-41bb-b200-d41689ffddc8")
	.graphSitePage()
	.publish();

Actual behavior

I can only do a GET from the graphSitePage point in the SDK, there is no publish() method.

Steps to reproduce the behavior

Use the POST to create a site page and then try to publish it via the SDK.
This is important because I used a app client secret, not myself, so I can't "see" the page in the Sharepoint UI when I log in as myself.

Start at the graphSitePage SDK entry point named in the example and review the functional tests under src/test/java/com/microsoft/graph/functional. Compare the available operations with the documented site-page publish endpoint. Done means the Java SDK supports publishing a created page and a test covers the operation.
