[Rule] Add `ignore_templated` option to LEN04 (too-long-test-case)

**Description**
I would like to configure rule 
* LEN04: too-long-test-case 

to skip test cases using `[Template]` syntax
The same as following rules (These already support `ignore_templated`)

* LEN05: too-few-calls-in-test-case
* LEN06: too-many-calls-in-test-case
