feat(tests): add @ignore annotation to end-point prompt test

Add @ignore annotation to end-point prompt test to temporarily exclude it from test suite.

This commit modifies the test file `PromptTemplateTest.kt` by adding the `@Ignore` annotation to the `should_fill_end_point_prompt` test function. This change is made to exclude this specific test from the test suite temporarily.
