feat: add import-deno as crate feature to import using .ts extension

[eythaann]

Goal

Allow to generate files compatible with Deno projects.

The --all-features test is failing due to the trim_end_matches problem mentioned above

[eythaann]

Fixed, just to note, I'm not able to run npx tsc like there's no package.json on the project.

Thanks for the fix! @NyxCode is there anything you'd like to add?
