add cloudwatch_event_rule_pattern_detail

[Hiroki6]

what

add cloudwatch_event_rule_pattern_detail variable to customize the event filter.
Basically a similar implementation of #59, which also added this variable.
Since the original PR has been open more than 1 year and seems to be stale, I opened the PR.

why

The default event pattern sends a lot of alerts.
This variable allows to customize the detail pattern to filter events.

This is not directly related to your PR, but can I ask you to address this issue to satisfy the failing checks for this output?

@Hiroki6 ah, the last thing:

not ok 1 check if terraform code needs formatting
# (in test file /test/terraform/lint.bats, line 9)
#   `[ -z "$output" ]' failed
+ status=fail
+ for test in $tests
+ printf '\n\nRunning output-descriptions in /__w/terraform-aws-security-hub/terraform-aws-security-hub/examples/complete\n'

...

 output "sns_topic" {
   description = "The SNS topic that was created"
-  value = module.example.sns_topic
+  value       = module.example.sns_topic
 }

Mind run terraform fmt against the code, please?
