chore(ci): run on default runners

[StarpTech]

It should no longer be necessary to run the router tests on big machines, since they have been sharded. This reduces cost.

Summary by CodeRabbit

• Chores
  • CI configuration updated to use the standard GitHub Actions runner for integration tests, improving consistency and resource efficiency.
• Bug Fixes
  • Improved validation around persisted-operations storage configuration so missing or mismatched storage providers now produce an immediate, clearer configuration error instead of failing later.

Checklist

• I have discussed my proposed changes in an issue and have received approval to proceed.
• I have followed the coding standards of the project.
• Tests or benchmarks have been added or updated.
• Documentation has been updated on https://github.com/wundergraph/docs-website.

Caution

Review failed

The head commit changed during the review from a3e161a to 1011e9c.

Walkthrough

Added a nil-check and explicit error when a configured persisted-operations storage provider ID has no matching storage client in router core; updated GitHub Actions integration_test runner from ubuntu-latest-l to ubuntu-latest. No other logic or exported declarations changed.

Changes

Cohort / File(s)	Summary
GitHub Actions Workflow Configuration .github/workflows/router-ci.yaml	Changed integration_test job runner from ubuntu-latest-l to ubuntu-latest (single-line runner config update).
Router core persisted-operations validation router/core/router.go	In buildClients, added a check that returns an error if persistedOperationsConfig.Manifest.Enabled is true and a non-empty storageProviderID is set but no matching pClient was found; prevents a nil dereference before pClient.ReadManifest(...).

1278-1280: Add a regression test for this new error branch.

Please add a PQL manifest test case for: explicit storage.provider_id set, no matching provider in storage_providers, and assert this exact startup error path.

In `@router/core/router.go` around lines 1278 - 1280, Add a regression test that
constructs a PQL manifest which sets storage.provider_id to a specific value
while leaving storage_providers without any entry for that ID, then invokes the
startup/manifest-validation entrypoint that exercises the code path that
resolves pClient (e.g., the router startup or manifest load function) and
asserts the returned error matches the exact message produced when pClient ==
nil: fmt.Errorf("storage provider %q is configured for PQL manifest but no
matching provider was found in storage_providers", storageProviderID). Use the
testing framework (testing.T with require/assert) to assert the error string
equality and reference the storage.provider_id value you used so the test
reliably triggers the pClient == nil branch.
