Environment variables example

``` // Add a list of actual environment variables available to the build here // Please keep the blank line above and below the code block // WARNING: Be careful not to include any private or otherwise sensitive information ```

Additional context Appflow is a continuous integration (CI) and continuous deployment (CD) platform for Ionic development teams. Appflow helps development teams continuously build and ship their Cordova, Capacitor, and React Native apps.

It appears there are no environment variables to uniquely identify ionic environment. All appears to be generic.

if ci-info is not able to detect ionic envioronment. may be we can use this CI_APP_ID or CI_BUILD_NUMBER or CI_BUILD_ID variables to detect whether it is CI or not. but this can't be used to detect whether if it is running actually on ionic.

ci-info should be now detect appflow https://github.com/watson/ci-info/pull/84. Keeping this open since this issue is not completely addressed.
