fix(ci): increase import profiler absolute threshold

[hebaalazzeh]

This PR implements static matrix sharding for the import-profiler workflow to run modified packages in parallel across 8 shards, and sets the absolute failure/timeout threshold for each package import check to 120s (2 minutes).

Key Changes

• Parallel Sharding: Updated .github/workflows/import-profiler.yml to split modified package execution across 8 GHA runner shards using basic bash modulo logic.
• Unified Status Check: Added an all-import-profiles status check that acts as the single required GitHub check.
• 120-Second Threshold: Set the absolute timeout threshold in ci/run_single_test.sh to 120000ms (120 seconds / 2 minutes).

Code Review

This pull request increases the --fail-threshold value from 5000 to 120000 in ci/run_single_test.sh when executing the profiler script. The feedback suggests double-quoting the ${PROFILER_SCRIPT} and ${PACKAGE_NAME} variables to prevent potential word splitting and globbing issues.

Can you create an example PR which includes changes to packages so we can see the results? Right now we only see No packages assigned to Shard 0. which is expected, but it would be great to see an example
