Add FAQ for setting genericVirusScannerTimeoutInSeconds configuration in the Runtime Malware Protection documentation

## What New Or Updated Would You Like To See?

At the moment, the only place that we mention the `genericVirusScannerTimeoutInSeconds` configuration is on the [main configuration page](https://docs.chocolatey.org/en-us/configuration). We've gotten a few questions about dependencies timing out when running into the default setting of 120 seconds.

## Why Is It Needed?

Since this is something several people have mentioned, it would be nice to have this information on the documentation page that specifically refers to malware protection and virus scanning.
