[REQUEST] Support setting version message for new Confluence pages

[kamakazikamikaze]

The Atlassian API supports setting version information as outlined in the documentation.

This library supports setting the version via .update_page() and .update_or_create() (for existing pages). However it doesn't support setting it through .create_page(). This is a request to add a keyword argument to the function which will allow passing it into the underlying POST JSON body.

This is only applicable to server/data center, I don't see this option in confluence cloud
