Feature: add pages support in project

[Karreg]

Description of the problem, including code/CLI snippet

I was not able to determine how to access to /api/v4/projects/:id/pages with python-gitlab. I'm not sure to have searched well, but the Projectobject does not seem to provide such access.

Would it be possible to add it?

The use case behind is I want to provide a public script to add a badge linking to the deployed pages, which requires such API access.

Specifications

• python-gitlab version: 4.4.0
• API version you are using (v3/v4): v4
• Gitlab server version (or gitlab.com): 16.9.2

Thanks for you great API wrapper, it's a real improvement over standard GitLab API!
