Accessibility bug: the nav elements across the theme should have an aria-label

[manish10]

Expected behavior

If there are multiple nav landmarks on a Web page, each nav landmark should have a useful aria label. This allows screen reader users to identify what each navigation landmark contains.

Steps to reproduce the behavior

actual result: None of the nav elements, including the skip links, the top nav in the masthead, and the previous/next nav in the blog post layout have an aria label or aria-labelledby in them to help identify the landmark. This is a WCAG violation.
All the sample pages for minimal mistakes also repro this problem.
