Use sidebar_label in pagination buttons.

[maxaggedon]

🚀 Feature

Display sidebar_label (if existing) of the previous and next docs instead of the title in bottom pagination buttons.

Have you read the Contributing Guidelines on issues?

yes

Motivation

If it has been set, sidebar_label is meant to be used for navigation (it could even be renamed nav_label). And it will certainly be shorter than title which will prevent some ugly UI cases...

Pitch

As a user I thought it would be the case. Why would I set an explicit label for navigation purposes and not see it in pagination?
I would be glad to work on a PR if the idea is accepted =)

Should be fixed in v1.5.1.

@huguestennier the PR you mention fixes a bug where the buttons always displays previous and next. With this fix, it displays the articles' title if existing. (Please correct me if I am wrong)

What I suggest is to display sidebar_label instead of title.
