Add sidebar menu to rules page

Thanks! I think this is a good idea, it could use a little design tweak so that the "Rules" content and the sidebar are centered on the screen. The sidebar could also get removed away on mobile, and I think it should be left un-ellipsis-truncated by default. The sidebar html could also be injected from the vite plugin instead:

publint/site/scripts/vitePluginMarkdown.js

Lines 58 to 64 in 1d24bf1

	async transformIndexHtml(html) {
	if (html.includes('<!-- rules.md -->')) {
	const markdown = await fs.readFile(rulesPath, 'utf-8')
	const rules = (await markdownProcessor.process(markdown)).toString()
	return html.replace('<!-- rules.md -->', rules)
	}
	},
