Fix broken Word Embeddings link in NLP lesson README (all translations)

[Karan Pathak (karanpathak)]

Summary

Fixes a broken link in the NLP lesson README caused by a typo in the directory reference (14-Emdeddings instead of 14-Embeddings). The same typo existed identically across all 55 translated versions of the README, so this PR corrects it everywhere for consistency.

Key Changes

• Corrected the Word Embeddings link in lessons/5-NLP/README.md from 14-Emdeddings/README.md to 14-Embeddings/README.md.
• Applied the same fix across all 55 translated READMEs under translations/*/lessons/5-NLP/README.md.
• Verified no remaining references to the misspelled Emdeddings path exist anywhere in the repo.
• Verified a 14-Embeddings directory exists under every translation's 5-NLP folder, so no corrected link is left dangling
