Fix react-native-windows documentation that fails with "^0.80.0" (#1143)

## Description
Problem Description
The
[react-native-windows](https://microsoft.github.io/react-native-windows/docs/getting-started)
page says that for creating a new project using the 0.80.0 version you
must run this command:

npx --yes @react-native-community/cli@latest init <projectName>
--version "^0.80.0"
However the following error appears:

error Cannot read properties of null (reading 'major').
TypeError: Cannot read properties of null (reading 'major')
