Fix dead links in README

[1t1sCooL]

Link-checked the README and fixed what is confirmed dead. Every dead URL was re-verified with curl (browser UA; NXDOMAIN double-checked via 8.8.8.8), and every replacement URL returns HTTP 200.

• http://angcosmin.com → https://github.com/AngCosmin
  • curl 000 + dig @8.8.8.8 empty (NXDOMAIN). Contributor link in all-contributors table; gh api users/AngCosmin returns the account with empty blog field, so the standard fallback is the GitHub profile of the same person.
• http://danielz.xyz → https://danielz.fyi
  • curl 000 + dig empty (NXDOMAIN). Same GitHub account (user id 65467530, renamed danielzsh->xyzqm) now lists blog danielz.fyi; page returns 200 and shows 'Daniel'/'danielz' branding — same person's site moved.
• http://mmshivesh.ml → https://github.com/mmshivesh
  • curl 000 + dig empty (NXDOMAIN, dead .ml Freenom domain). gh api users/mmshivesh: account exists, blog field empty — replace with the same contributor's GitHub profile (all-contributors fallback).
• http://pribess.github.io → https://github.com/Pribess
  • curl -L returns 404 (GitHub Pages site removed). gh api users/Pribess: account exists, blog field empty — replace with the same contributor's GitHub profile.
• https://akringblog.com/ → https://akring.com/
  • curl 000 + dig empty (NXDOMAIN). Same GitHub user akring now lists blog https://akring.com/; it returns 200 with title 'Akring' — same person's site on a new domain.
• https://alexsinelnikov.io/ → https://alexsinelnikov.blog
  • curl 000 + dig empty (NXDOMAIN). Same GitHub user avdept (Alex Sinelnikov) now lists blog https://alexsinelnikov.blog; it returns 200 (personal product-developer blog) — same person's site moved.
• https://ninjiacoder.me → https://rayzhao.work
  • curl 000 + dig empty (NXDOMAIN). Same GitHub user RayZhao1998 now lists blog https://rayzhao.work; it returns 200 with title 'Ray Zhao | AI Coding、iOS 与产品工程' — same person's site on a new domain.
• https://nobelliu.github.com → https://github.com/NobelLiu
  • curl 000, dig empty (*.github.com subdomains do not resolve; the likely intended nobelliu.github.io is also 404). Profile blog field still holds the dead URL — replace with the same contributor's GitHub profile (verified via gh api).
• https://wdg.codes → https://wesleydegroot.nl
  • curl 000 + dig empty (NXDOMAIN). Same GitHub user 0xWDG now lists blog https://wesleydegroot.nl; it returns 200 with title 'Home - Wesley de Groot' — same person's site on a new domain.

Happy to adjust or split this if you'd prefer a different fix for any item.
