Problem

apps/test-suite/README.md links to the project's main contributing guide with a single-dot-dot relative path:

Please refer to the project's main [CONTRIBUTING.md](../CONTRIBUTING.md) file for guidelines...

From apps/test-suite/, ../CONTRIBUTING.md resolves to apps/CONTRIBUTING.md, which does not exist. The only CONTRIBUTING.md in the repo lives at the root, so the link 404s on GitHub (and anywhere the README is rendered relative to its own path).

Fix

Point the link one more level up so it reaches the root file:

[CONTRIBUTING.md](../../CONTRIBUTING.md)

The surrounding sentence already says "the project's main CONTRIBUTING.md", so the intended target is unambiguously the root file.

How to verify

From the repo root:

# broken target (what the current link points at) -> absent
test -f apps/CONTRIBUTING.md || echo "apps/CONTRIBUTING.md: MISSING"
# fixed target -> present
test -f CONTRIBUTING.md && echo "CONTRIBUTING.md (root): OK"

Or open apps/test-suite/README.md on GitHub and click the link before/after: ../CONTRIBUTING.md 404s, ../../CONTRIBUTING.md lands on the root guide.

Docs-only, one line changed.

Summary by cubic

Fixes the broken relative link in apps/test-suite/README.md so it points to the root CONTRIBUTING.md instead of the non-existent apps/CONTRIBUTING.md.
