chore: Update vite-plugin-tailwind-purgecss and PurgeCSS docs

[AdrianGonz97]

Description

vite-plugin-tailwind-purgecss purging strategy has been overhauled and released as of version 0.3.0: AdrianGonz97/vite-plugin-tailwind-purgecss#27 (also includes a migration guide)

This PR updates the vite plugin to its latest version and it also updates the installation instructions for the purgecss docs page.

---

CSA also needs to be updated to remove this section as it's no longer needed:

skeleton/packages/create-skeleton-app/src/creator.js

Lines 227 to 238 in 986ff4c

	if (opts.codeblocks) {
	contents += `{
	safelist: {
	// any selectors that begin with "hljs-" will not be purged
	greedy: [/^hljs-/],
	},
	}),
	],
	});`;
	} else {
	contents += `)]
	});`;

However, I noticed that the versions (0.0.53) in the package.json is out-of-sync with the published version on npm (0.0.54): https://www.npmjs.com/package/create-skeleton-app, so I've left that out of this PR. Any guidance on how to go about this @niktek?
