lightning-flow-scanner fails for salesforce flavor due to sf cli reporting update availablee

lightning-flow-scanner fails due to the sf CLI outputting a new version being available and therefore the following regex failing

```
Unable to extract version with regex re.compile('(?<=lightning-flow-scanner )\\d+(\\.\\d+)+') from  ›   Warning: @salesforce/cli update available from 2.48.6 to 2.49.7.
```

To reproduce just use the SF flavor of megalinter on a salesforce repo
