- Quote headline/description/name in JSON-LD with jsonify for valid JSON
- Fix pagination section filter from "blog" to "posts"
- Fix .Params.category to .Params.categories to match front matter
- Quote content attributes on published_time meta tags
- Add missing space after `with` in template tags
- Replace deprecated tweet shortcodes with x (8 instances across 3 posts)

 But to be honest, I didn't feel confident to take my exam after finishing all the learning paths. It was too theoretical for me, especially for an expert level exam. Because I had many doubts, I asked the Cloud community recommendations to finish my preparation, and many people recommended me CloudSkills. So I decided to give it a try!

 It's probably the most challenging exam I have prepared so far. I worked on it every single day from June to September at least one hour per day. The funny thing is back in June, I was still new to Azure, and it took me 150 days to pass the exam.
