undici before v5.8.0 vulnerable to CRLF injection in request headers

Details

### Impact

It is possible to inject CRLF sequences into request headers in Undici.

```js const undici = require('undici')

const response = undici.request("http://127.0.0.1:1000", { headers: {'a': "\r\nb"} }) ```

The same applies to `path` and `method`

### Patches

Update to v5.8.0

### Workarounds

Sanitize all HTTP headers from untrusted sources to eliminate `\r\n`.
