Still unable to import yaml.

### Expected Behavior

I imported JSON (v4) template to the insomnia, and then exported it with v5 template, and then when I reimport this, I want to see correct collection.

### Actual Behavior


I cannot import V5 template based on the V4 template.

Start by reviewing issue #8529 and reproduce the V4 JSON import, V5 export, and reimport flow in Insomnia 11.1.0 on macOS 15.4.1. Done means the converted V5 template imports successfully and displays the correct collection.
