docs(Page): add example showing different type prop variants

[adamviktora]

What: Closes #9868

Additional issues:

• Section with type="nav" for tertiary navigation: the tertiary navigation was removed in V6, we should rename it in the upcoming React example for V6 and the Core V6 example too - but what is the type="nav" used for in V6 if not tertiary navigation?

Just to note: it seems like our preview builds are having issues, I didn't see this example on the preview but I did see it locally. That local build did show some compilation warnings, but I'm guessing those aren't related to this PR.

It looks like the example is missing the -group section that exists in the core version, but I see that seems to be missing as an option of PageSection so that could be done under a different issue IMO.

Other than wanting that addressed or a followup created and issues brought up in the PR body LGTM, happy to approve once those are resolved.

Yeah, the example is missing in the preview for some reason. In all the new branches I base on current main I see this compilation warning related to the new Dropdown template:

I don't know if it is related to why the example is not showing in the preview though.

About the -group section, as you say, it is not a type prop option of the PageSection, but a PageGroup component, and there is an example already for that. So I did not include the PageGroup there on purpose.

Locally, this looks good to me. I'm investigating the pr-preview situation 👍🏻

#10416 should fix this problem, let's do a rebase of this PR to see if it resolves the issue.
