refactor: streamline RSS feed generation

[L4Ph]

This pull request removes the markdown-it dependency and its related packages, replacing its functionality with a custom implementation for processing blog posts in the RSS feed. The changes focus on dependency cleanup and code refactoring.

Dependency Cleanup:

• Removed the markdown-it dependency from package.json and pnpm-lock.yaml, along with associated packages like linkify-it, mdurl, punycode.js, and uc.micro. These packages were no longer needed after the refactor. [1] [2] [3] [4] [5] [6] [7] [8] [9] [10] [11] [12]

Code Refactoring:

• Updated the RSS feed generation in src/pages/rss.xml.ts to replace the markdown-it parser with a new approach using compiledContent() for rendering post content. This also introduced a custom filtering and sorting mechanism for blog posts based on their metadata.

Normally, post.url would return correctly without doing this.

	const postsWithUrls = sorted.map((post) => {
		const contentPath = path.relative(process.cwd(), post.file);
		let url = contentPath
			.replace(/^src\/content/, "")
			.replace(/\.md$/, "")
			.replace(/index$/, "");

		url = url.replace(/\\/g, "/");
		if (!url.startsWith("/")) {
			url = `/${url}`;
		}
		if (!url.startsWith("/posts/")) {
			url = `/posts${url}`;
		}
		return {
			...post,
			url: url,
		};
	});

I think it's a relatively neat solution (just tweaked the official sample).
Would you like to try this branch?

But on my windows:

I tried clone again,but the same problem

[SakuraSenQwQ]

I see：
:36 .replace(/^src/content/, "")
TO
:36 .replace(/^src[/\]content/, "")

On Debian：

Maybe we need to select and keep part of it

Now, opening a Pull Request is one thing, but honestly, the code feels downright terrible.
Since #492 represents a fairly solid fix, we'll merge that instead.
