Detection of yarn does not work (anymore?)

Nessuno ha ancora preso questa issue.

### Describe the bug

While loopback-cli tries to detect yarn a file `yarn-error.log` is generated. It seems that yarn cannot write to it's stdout when it is spawned as a child process by `lb4`.

### Logs

```shell
yarn-error.log:

Arguments:
/snap/node/7382/bin/node /snap/node/7382/bin/yarn.js help

### Additional information

This issue can be fixed by using `stdio: 'ignore'` instead of `stdio: false` here: https://github.com/loopbackio/loopback-next/blob/9d99c620e7dedad9099e1c83a068216c198749e0/packages/cli/lib/utils.js#L768

### Reproduction

none

Inizia da packages/cli/lib/utils.js, intorno alla riga 768, dove yarn viene avviato durante il rilevamento, e confronta l'impostazione stdio attuale con la modifica suggerita nell'issue. Verifica che il rilevamento di yarn non produca più yarn-error.log né un errore EACCES di stdout quando viene eseguito come processo figlio di lb4; non vengono forniti né una riproduzione né un file di test.
