Nested runme (running runme as part of a cell/block) garbles init sequence

[sourishkrout]

Running $ runme --filename garble.md run garble inside of https://github.com/stateful/vscode-runme with following markdown produces output with the runme init sequence garbled (screenshot below).

---
runme:
  id: 01HPF9RK4ANXWGH3DRF4SV7CZR
  version: v2.2
---

```sh {"id":"01HPF9RNHT3RSAGWA4CR4HKRS8","name":"garble"}
npx runme run test:format test:lint test:lint:fix
```

Visual problem:

@adambabik is it safe to assume that above's issue will be fixed by completing the switch to runnerv2 (#474)?

I tested it quickly and it looks ok with run-locally. I think you can test it yourself:

# in /path/to/github.com/stateful/vscode-runme

$ runme --version
runme version 2.2.6 (Homebrew) on 2024-02-09T17:53:40Z

$ runme --filename CONTRIBUTING.md run-locally test
 ►  Running task test:format...
nvm is not compatible with the "npm_config_prefix" environment variable: currently set to "/usr/local"
Run `unset npm_config_prefix` to unset it.
Checking formatting...
src/client/components/terminal/share.ts

The output of run-locally is not distorted, unlike run.
