jsdoc rendering summary can end with a `:`

[crowlKats]

In some cases, a JSDoc summary can end with a :. We should change this by backtracking to a . if one is present and only show the content until then, else still show the summary as-is.

The relevant part of the codebase is

deno_doc/src/html/jsdoc.rs

Lines 392 to 418 in 93f4ce3

	fn walk_node_title<'a>(node: &'a AstNode<'a>) {
	for child in node.children() {
	if matches!(
	child.data.borrow().value,
	NodeValue::Document
	| NodeValue::Paragraph
	| NodeValue::Heading(_)
	| NodeValue::Text(_)
	| NodeValue::Code(_)
	| NodeValue::HtmlInline(_)
	| NodeValue::Emph
	| NodeValue::Strong
	| NodeValue::Strikethrough
	| NodeValue::Superscript
	| NodeValue::Link(_)
	| NodeValue::Math(_)
	| NodeValue::Escaped
	| NodeValue::WikiLink(_)
	| NodeValue::Underline
	) {
	walk_node_title(child);
	} else {
	// delete the node
	child.detach();
	}
	}
	}

I'd be interested in working on this but could you help provide an example of what the output is currently and what it should look like? Thanks!

@c43721 sure. for example:
https://docs.deno.com/api/node/child_process/~/exec

The summary currently renders like this:

However since it ends with :, it should backtrack, so it should end up being this
