# What does this PR do?
Updates the script `scripts/check-workflows-use-hashes.sh` to improve
error reporting by adopting GitHub Actions error annotation format.
* Updated the script to use GitHub Actions error annotation format
(`::error file={name},line={line},col={col}::{message}`) making error
messages more actionable and easier to locate in workflows.
* Modified the script to include line numbers for `uses:` references by
using `grep -n` and extracting line numbers, improving the precision of
error reporting.
Closes#2778
## Test Plan
- Violation check - Created test file with mixed SHA/non-SHA actions
```
echo 'uses: actions/checkout@v4' > test-workflow.yml
echo 'uses: actions/upload-artifact@main' >> test-workflow.yml
```
Result: Correctly detected violations with precise line numbers
```
./scripts/check-workflows-use-hashes.sh
Output:
::error file=test-workflow.yml,line=14::uses non-SHA action ref: uses: actions/checkout@v4
::error file=test-workflow.yml,line=20::uses non-SHA action ref: uses: actions/upload-artifact@main
```
- Verified existing project workflows pass
```
./scripts/check-workflows-use-hashes.sh
# Result: Exit code 0 (all workflows properly SHA-pinned)
```
