TGUI: bumps yarn version (#82385)

Bumps our bundled yarn version up to 4.1.1.

This seemed previously impossible due to an indecipherable error
message:
```
SyntaxError: missing ) after argument list
    at wrapSafe (internal/modules/cjs/loader.js:979:16)
```

I'm assuming this was a bug in (earlier) versions of yarn ~4.0.2.
Meaning, this is probably worth testing or test merging, as it seems to
be running fine currently.
