* Fix various style/template issues
- Add styles to allow fully invisible headers. These can be used to
support anchor links in translated pages, so we can move the link_subs
out of the dactyl-config.yml. Example in transaction-common-fields.md
- Upgrade jQuery to 3.7.1
- Add left nav to references landings for consistent navigation
- Add breadcrumbs template (previously used Dactyl built-in) which
throws an error if you specify a parent: that doesn't exist.
(Previously it would write a blank link; the link checker would
report this as an error, but it wasn't obvious what the cause was.)
- Fix#2014 (special case for code blocks nested in lists).
- Fix#2096.
- Remove excessive spacing between top nav and main content, and
re-align top of main contents in all 3 columns for docs pages.
- Reorganize _content.scss to be easier to read.
