'''typescript keeps appearing in my typescript files, I wonder if being generated by Bolt/Stackblitz?

[tomwattsuk]

Describe the bug

I've noticed in some files i'm seeing at the top:

````typescript`

and then at the end

I'm not sure what is going on here, these are files i'm not touching to my knowledge, but then when i run a build they'll error and i'll have to remove the errornous code - and then i will see it generated again at some point? 

Any thoughts? 

### Link to the blitz that caused the error

https://stackblitz.com/edit/sb1-yz9yvjqu?file=package.json

### Steps to reproduce

Afraid it's just random

### Expected behavior

I can't add this field i'm afriad

### Parity with Local

- [X] I have [run the project in my local machine](https://github.com/stackblitz/webcontainer-core/blob/main/repro.md#try-locally) and I could not reproduce the issue.
