* ci: add local mkdocs-admonitions plugin for prettier to allow admonition preservation
* docs: remove uses of `prettier-ignore` for admonitions
* test: rather use await expect
* chore: use named group exclusively
* docs: ensure 2 spaces used for generated admonitions
As a follow-up to 4b0146ab7b and
1844916259b6dc17f532e491eb93f6116327c324., this correctly renders
admonitions with 2 spaces (1 indent).
* fixup! docs: use 2-space indentation for Markdown (#43537)
Plus using 3-space for mixed-style `<ul>` and `<ol>`s.
* fixup! docs: use 2-space indentation for Markdown (#43537)
As otherwise it breaks the rendering of the table.
