Implement option to run terraform-change-pr-commenter also on context.eventName "workflow_call"

[developer2048]

Hello,

thanks for this tool. We use it in a lot of pipelines.
But some of our pipelines are splitted and communicate through workflow calls. So if a new PR is opened, it triggers another workflow over a workflow_call and in this second workflow the "terraform plan" will run. But the terraform-change-pr-commenter will not be triggered in the second workflow, because the "context.eventName" has changed (to "workflow_call").
Would it be possible to add "workflow_call" also as trigger for the PR commenter? Thanks a lot!

See here:

I opened a pull request to implement it.
