Fix SEO issues to impove the Ahrefs' Health Score

[nqst]

Made some changes that should improve our SEO Health Score provided by Ahrefs. As of Dec 2023, the score was 87%.

Changes:

• Fixed broken links.
• Added og:image and other Open Graph & Twitter tags.
• Added meta descriptions for the website pages. I didn't add the descriptions to all blog posts, but added an example one to the most recent post.
• Fixed the Noindex page in sitemap issue.
• Optimized a heavyweight image.

Unrelated change: running yarn inject:protocol added some changes to the protocol that weren't added before.

That's amazing @nqst 👏

Is the example blog post description ok to go live with or should someone (@Acconut?) write descriptions for each post?

Is the example blog post description ok to go live?

Yeah, that's just an excerpt from the blog post introduction, so it should be good to go.

Should someone write descriptions for each post?

Ideally, yes, although that's a secondary priority compared to adding descriptions to the homepage and the pages that we have in the navbar.
