Fix Dependabot configuration - missing labels cause PR creation failures

**Problem:**
Dependabot configuration references labels 'dependencies' and 'npm' that don't exist in the repository, causing PR creation to fail.

**Evidence:**
Dependabot comments in PR #2 show: "The following labels could not be found: `dependencies`, `npm`"

**Impact:**
Dependabot cannot properly label dependency update PRs, reducing maintainability.

**Solution:**
Either create the missing labels or remove them from `.github/dependabot.yml`

Start with .github/dependabot.yml and inspect PR #2 for the reported label errors. Confirm whether the dependencies and npm labels exist in the repository, then choose the documented configuration approach. Done means Dependabot can create dependency update PRs without reporting missing labels.
