x/pkgsite: heading parsed incorrectly in documentation overview

[julieqiu]

What is the URL of the page with the issue?

https://pkg.go.dev/cmd/go/#hdr-Import_path_checking is the closest anchor link.

https://pkg.go.dev/cmd/go/#hdr-Modules__module_versions__and_more is the expected URL.

What is your user agent?

Mozilla/5.0 (Macintosh; Intel Mac OS X 11_2_1) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/88.0.4324.182 Safari/537.36

Screenshot

What did you do?

What did you expect to see?

Modules, module versions, and more is a heading, as is the case on https://golang.org/cmd/go/#hdr-Modules__module_versions__and_more.

What did you see instead?

Modules, module versions, and more is not a heading.
