Fix init command in generateTestApp method to use new @react-native-community/template package

[Yajur-Grover]

Summary

This PR edits the init command to use the new template at @react-native-community/template. Currently, it is set to use the next version, as there is a big discrepancy between the nightly build versions available on the react-native package and new @react-native-community/template package.

This PR adds a job that will publish a nightly build to the @react-native-community/template package every time a new react-native package is published. Once the react-native-windows repo is integrated up to the same date, we will revert the 'next' to 'reactNativeVersion'. This pending change is tracked in the following issue: microsoft/react-native-windows#13446

Test plan

1. Change the create-react-native-library.cmd line 3 to the following:
   node "%~dp0\create-react-native-library" %* --slug testcli --description testcli --author-name "React-Native-Windows Bot" --author-email [email protected] --author-url http://example.com/ --repo-url http://example.com/ --languages java-objc --type module-new --react-native-version 0.75.0-nightly-20240618-5df5ed1a8 --example vanilla testcli
2. Run yarn watch
3. Run packages/create-react-native-library/bin/create-react-native-library

I don't understand what's the issue here - when you pass --react-native-version next to CRNL it should use react-native@next which currently contains a logic for downloading template from react-native-community/template.

Yes I applied a more approriate fix to our CLI test in our React Native Windows repo - this change is not necessary.
