Provide text entry for VPDocFooter

[userquin]

Is your feature request related to a problem? Please describe.

When the text on the link is contextual there is no way to include an alternative text to be shown on next/prev footer.

Describe the solution you'd like

Add an optional text entry on SidebarItem and use it on VPDocFooter if configured.

Describe alternatives you've considered

Additional context

We have a Getting Started on each group:

Here you can check the text is not in context (the next entry should be Getting Started | Frameworks):

I like the idea. For design, I think we can learn from this 👀

A late rendering. I think this is a bit more visible than the gitbook one

@kiaking @kecrily I configure the title this way Title | Section on frontmatter section (like on the last screenshot), maybe you can access to it and use it on the next/prev links, if possible: just add also a hint on the docs.

This way you only need to change how to get the title from fontmatter, the layout will be the same.

Just check this https://github.com/antfu/vite-plugin-pwa/blob/main/docs/guide/index.md (any other page is configured this way on pwa repo)

EDIT: the logic should apply when the context changes, if applied always maybe there is no space to add the title.
