Translated security-best-practices-for-your-project.md into Hindi

Updated the Hindi security-best-practices article with a polished translation, removed the untranslated: true marker preserving the original article structure, metadata, links, aside, and contributor credits.

Note: the Hindi translation is already live; just one article was remained untranslated. This PR only updates the article content from untranslated English to Hindi.

Thanks for taking this on, @gaurav7902! Structurally this looks great:

• Heading parity matches the English source exactly (11 ##, 13 ###)
• Frontmatter title and description are translated
• The untranslated: true flag was correctly removed now that this article has been translated
• Technical terms (SAST, SBOM, OWASP, GitHub, Node.js, MFA, etc.) sensibly kept in English
• Existing cross-article anchor link (legal/#which-open-source-license-is-appropriate-for-my-project) preserved

Heads-up: I am not a native speaker of this language, so I have leaned on AI to help spot-check the translation rather than verify fluency end-to-end.
