feat: Add support for @ts-ignore flag

[milutin]

This pull request activates pre-existing, but previously disabled, support for the // @ts-ignore flag. This feature allows
developers to suppress diagnostics for specific template expressions.

The underlying logic for this functionality was already prepared in the codebase. This change simply enables it and adds a
corresponding test case to ensure it works as expected.

Changes

• Uncommented and enabled the logic in find-tagged-templates.ts that checks for the // @ts-ignore comment before analyzing a
  tagged template expression.
• If the comment is found, the expression is skipped, and no diagnostics are emitted for it.

Testing

• Added a new test case in no-unclosed-tag.ts to verify that diagnostics are correctly suppressed when the // @ts-ignore flag is
  used.
• All existing tests continue to pass, confirming no regressions were introduced.

Awesome! Thanks @milutin!

My only question is why this was commented out. Did you happen to find the commit where it was, and maybe an explanation for it?
