headings do not increase in increments of 1

[noraegloff]

Heading levels should be hierarchical, only increasing by 1. This ensures the order of headings is semantically correct. In testing, the repository homepage threw this error, and it was also found on Collection homepages, the Browse Collections pages, and on the Catalog page.

See the Deque aXe help page for this error.
