Is your request related to a new offering from AWS?

Is this functionality available in the AWS provider for Terraform?

• Yes ✅: https://registry.terraform.io/providers/hashicorp/aws/latest/docs/resources/vpn_connection#enable_acceleration

Is your request related to a problem? Please describe.

To use Global Accelerator for low latency and high throughput, you can enable acceleration on site-to-site VPN connections.

Describe the solution you'd like.

An option enable_acceleration would be great that, maybe in combination with a check if connect_to_transit_gateway is set as this is only usable with tgw.

Describe alternatives you've considered.

Can't see any.
