The macro works fine for the current help center. But for the new help
center, the macro has a paragraph tag already, when it is part of a list
item, the margin inserted by starlight causes spacing issue. We can
override the margin for this specific case when we have the ability to
modify the MDX directly. Issue for that: #35407. Until then, we remove
this macro since it's only used it two places to have proper spacing.
Our help-beta conversion script expects text to be indented if the text
is part of the same list item. If it is not part of the same list item,
then it expects an empty line just after the list item. This commit
fixes existing instances for the same by searching for regex: `^1\.
.*\n(?!\n)(?!1\.)( {0,1}\S.*)`.
We do not want to add a lint rule for this, since not indenting is not
technically wrong. We will add a TODO list item in the conversion script
for help-beta in future commits.
These files are not Jinja2 templates, so there's no reason that they needed
to be inside `templates/zerver`. Moving them to the top level reflects their
importance and also makes it feel nicer to work on editing the help center content,
without it being unnecessary buried deep in the codebase.
