fix: warn only in init command when CLI uses cached npx version (#…

…44644)

Summary:
In #37510, a check was introduced to check if user is using `latest` version of `npx`, but right now it checks for every command executed, but it should only ensure that `latest` is included when creating a new project.

In this Pull Request I've added a condition to only warn if `init` was fired.

[GENERAL] [FIXED] - Warn only in `init` command when CLI uses cached `npx` version

Pull Request resolved: #44644

Test Plan: Warning about using `latest` version CLI should only be presented when running `init` command.
