Add the ability to set "propagate_at_launch=true" on tags added to aws_autoscaling_group Terraform resources.

Is your feature request related to a problem? Please describe.
We use tags to track costs across our infrastructure, linking them back to specific git_repos (using the git tags added by yor). However, EC2 instances launched through an AWS autoscaling group do not receive those tags (and can therefore not be tracked).
AWS autoscaling groups have the "propagate_at_launch" property that can be added to individual tag blocks in the aws_autoscaling_group module (but not in a plural "tags" mapping), causing the EC2 instances to get a copy of the specified tags from the autoscaling group.

Describe the solution you'd like
Adding tags to autoscaling group resources as individual "tag" blocks (instead of a "tags" mapping) and adding the option to set the "propagate_at_launch" property on them for the standard git tagger would be very useful for tracking dynamically created resources.

Describe alternatives you've considered
The workaround is to manually add a tag block to an autoscaling group resource with a static or derived value, without making use of Yor and the repository values it computes, but this is manual and error-prone work.
