fix(@schematics/angular): improve comment preservation in jasmine-to-vitest

This commit improves the preservation of comments during the `jasmine-to-vitest` transformation.

Specifically, it fixes an issue where multi-line comments between chained spy calls were being discarded. The transformer has been updated to use a less destructive AST modification pattern, which successfully preserves this trivia.

Additionally, a previously failing test case for this scenario has been re-enabled and is now passing.
