Auto add Admin prefix only for Admin nodes.

[jtkech]

Fixes #13943

We recently updated the NavigationManager so that admin menu items are auto prefixed by the AdminUrlPrefix option if not yet done, but as stated by @Piedone #12807 (comment), currently the auto admin prefixing should only be done for menu items built by the LinkAdminNodeNavigationBuilder.

This to not break people using the NavigationManager with other menu nodes but not for admin menus.

@hishamco NavigationManager is used elsewhere than just the admin UI. I use it to build frontend dynamic menus.

We do that too with Lombiq Base Theme.

Did I ask a question or write a comment about this?

[Skrypt]

You just did ask a question 😄
Not sure what you mean there.

I was OFF for a week, I was surprised when you mentioned me while I didn't ask a question or write a comment, maybe I asked somewhere else

I think this is fine for constants

[jtkech]

Yes I agree, but Visual Studio shows a warning, because of the new rule we have on private fields (leading underscore required) in the editor config, maybe there is a way to exclude private const from this rule. Note: We also have warnings on private localizer fields as S and H.

[jtkech]

Okay I reverted the renaming of this const

I suggested here #13953 to ignore the underscore rule for private const.
