Update main.tf and variables.tf

This commit updates the main.tf and variables.tf files.

In main.tf:
- The regions in the data "aws_ip_ranges" block have been formatted for better readability.
- The data "dns_a_record_set" block has been corrected to use double quotes for the block name.
- The local.proxy_vars block has been indented properly for better readability.
- The security_group_ids attribute in the resource "aws_vpc_endpoint" block has been formatted for better readability.
- The extra_environment_vars attribute in the module "github-runner" block has been formatted for better readability.
- The runner_labels attribute in the module "github-runner" block now converts the var.repo_org value to lowercase.

In variables.tf:
- The variable "create_ecs_cluster" has been properly defined with double quotes for the block name and correct indentation.

No issues were found in the versions.tf file.
