Fix AWS get_price action to use assumed role credentials

[ravikiranvm]

Fixes OPS-3871.

Additional Notes

We were passing raw auth from context in get_price runtime instead of resolving credentials first.
When a connection is configured with only assumeRoleArn (no access key/secret), the Pricing call could fall back to host/default credentials under implicit-role mode. That caused pricing action to run under an unintended principal and fail with permission errors.

Pull request overview

This PR updates the AWS get_price action to use resolved/assumed-role AWS credentials (via getCredentialsFromAuth) when querying the Pricing API, aligning runtime behavior with how credentials are already handled in the action’s property option loaders.

Changes:

• Resolve AWS credentials from context.auth before calling getPriceListWithCache.
• Update the unit test to assert getPriceListWithCache is called with resolved credentials rather than the raw auth object.

• getPriceListWithCache is an async function; calling it without await inside this try block means promise rejections won't be caught by the surrounding try/catch, so the action may throw an unwrapped error instead of the intended "An error occurred while fetching prices" message. Await the call (or return await ...) so errors are handled consistently.

      const priceList = getPriceListWithCache(
        credentials,
        service.ServiceCode!,
        filters,
        PRICING_REGION,
      );
