fix: move away from lambda environment variable due to size constraints

https://github.com/philips-labs/terraform-aws-github-runner/issues/3594

Renamed the variable runner_config to queues_config only for internal webhook module as there was inconsistency in naming this variable between lambda and terraform code.

I did come across this issue https://github.com/philips-labs/terraform-aws-github-runner/issues/3546 while testing this change and after adding all kms permissions(kms:*) to scale-up lambda, it started working.

Also this issue https://github.com/philips-labs/terraform-aws-github-runner/issues/3422 is also pointing at the same problem. @npalm lets synch on this issue and try to address it as I could reproduce it with multi runner example.

Update on kms issue:

After investigating further we found that the kms issue occurs if the corresponding AWS account EC2 settings is configured to use EBS with encryption.
