Is your request related to a problem? Please describe.

Currently rule creation has a 5m timeout, https://registry.terraform.io/providers/hashicorp/aws/latest/docs/resources/security_group_rule#timeouts

I'm noticing that rule creation is slow for some reason, going past this 5m timeout in our west region. This is causing problems for us as the plan after will try to create it again even though AWS already has the rule available after our first apply times out.

Describe the solution you'd like.

I can create the PR too if you'd like, there is currently a create_timeout variable, I'm leaning towards reusing that create_timeout variable for consistency and passing it into the rule creation timeouts

Describe alternatives you've considered.

Plan / apply again after aws created the rules after the timeout, this actually lead to failures where plan tries to recreate the same rules that is out already and failing as they are in console.
