util: unify post data structure

[Drew-Macgibbon]

I will check the data structure of these blogs and create a unified data structure:

• https://skyandtelescope.org/astronomy-blogs/ - good option
• https://blogs.esa.int/- good source, similar to nasa
• https://www.space.com/ - good source
• https://astrobiologysociety.com/blog/ - semi-difficult to scrape, ignore for now
• https://ras.ac.uk/news-and-press - semi-difficult to scrape, ignore for now
• https://arxiv.org/archive/astro-ph - academic papers in PDF, ignore for now
• https://www.seti.org/news?page=0 - good option
• https://www.home.cern/ - good option

Working data structure:

export const NewsValidation = z.object({
  id: z.number(),
  created_at: z.string().nullable(), // need to use the date of actual post
  updated_at: z.string().nullable(), // need to use the date of actual post
  title: z.string().nullable(),
  link: z.string().nullable(),
  category_id: z.number(),
  tags: z.array(z.object({
    id: z.number().optional(),
    name: z.string()
  })).optional(),
  author: z.object({
    name: z.string(),
    link: z.string().nullable(),
    image: z.string().nullable()
  }).nullable().optional(),
  raw: z.object({
    title: z.string().nullable(),
    imageCaption: z.string().nullable(),
    credits: z.string().nullable(),
    imageAlt: z.string().nullable(),
    content: z.string().nullable()
  }).optional(),
  media: z.array(
    z.object({
      url: z.string().nullable(),
      alt: z.string().nullable(),
      caption: z.string().nullable()
    }).nullable().optional()
  ).nullable().optional(),
  summary: z.object({
    beginner: z.string().optional(),
    intermediate: z.string().optional(),
    expert: z.string().optional()
  })
})
