DOC-6360 make sure command lists and code examples appear correctly in .md pages

[andy-stark-redis]

The shortcodes for the new command lists in the data type pages, some of the code examples and multitabs were not being handled correctly for the Markdown output (so they appeared in the output files as shortcodes). Now fixed, so if you look at the GET page, you should see the command list (as a table) and the examples and multitabs without any shortcodes.

Another fiver at the ready, btw :-)

Note

Medium Risk
Touches core Hugo templates/partials that generate .md outputs, so regressions could affect many pages’ rendered content and metadata, though changes are limited to documentation rendering logic.

Overview
Fixes Markdown export rendering so pages no longer leak Hugo shortcodes into the generated .md output. The single.md/section.md pipeline now handles escaped shortcode forms, runs additional expansion passes for command-group and multitabs, and only strips remaining shortcodes after unescaping entities (including + to +).

Replaces TOC generation from toc-json-regex.html to a new toc-from-markdown.html that derives ##/### headings directly from .RawContent. Updates markdown-code-examples.html to better normalize code-fence languages and to support self-closing clients-example shortcodes, emitting fully expanded, AI-friendly Markdown sections.

LGTM. Just one comment: I don't see the API method information in the html.md file. Maybe that's by design.

I'm in a good mood this morning, so this one is on the house. :)

@dwdougherty Thanks, I'll have a look at that (I don't think it's by design but I'll check).
