Ability to define initially selected page, other than type: 'main'

It'd be awesome if GrapesJS could take a configuration option with the pageManager that would identify which page should be selected. Reason being, if a system uses GrapesJS only for content editing then the page being edited is given going in into the editor.

I'd be glad to review and merge the PR.
I guess it would be a matter of adding a new selected?: string (page id) option to PageManagerConfig and try to use it PageManager.postLoad method

EDIT: ah it's already here 😅

I have no problem with renaming the activePage to selected but I think the problem that I am trying to solve here is to have the right page selected by default without going through the {type: 'main'} one. I think going with postLoad will make 2 page selections instead of one, and that is what I am trying to avoid.

Without selecting the page in PageManager.postLoad it won't select it if the project is loaded asynchronously (eg. from a remote Stoage)
