docs: fix C4A-Script documentation links in the tutorial READMEs

[pratikgx]

Summary

The "C4A-Script Documentation" and "API Reference" links at the end of both C4A-Script tutorial READMEs are broken.

• docs/examples/c4a_script/tutorial/README.md: ../../md_v2/... resolves to docs/examples/md_v2/..., which doesn't exist. Now ../../../md_v2/....
• docs/md_v2/apps/c4a-script/README.md: the same links resolve to docs/md_v2/md_v2/.... Since this copy already sits inside md_v2/, they're now ../../core/c4a-script.md and ../../api/c4a-script-reference.md. That also fixes them on the docs site, as the file is inside the mkdocs folder.

List of files changed and why

• docs/examples/c4a_script/tutorial/README.md: fix 2 relative links
• docs/md_v2/apps/c4a-script/README.md: fix 2 relative links

How Has This Been Tested?

Docs only. Both targets (docs/md_v2/core/c4a-script.md and docs/md_v2/api/c4a-script-reference.md) exist on develop, and every relative link in both files now resolves.
