Upgrade NodeJS version

Upgrade NodeJS version from 16 (now deprecated) to 20

Focus on Fastlane execution

This version removes some functionality that should rather be covered by a preceeding ruby/setup-ruby setup in your workflow. See README for all the details.
The release also removes any remaining usage tracking code.

Increment Node Version

Incremented Node version to Node 16 (fixes #98)

Disable usage tracking by default

Because of an issue with the usage tracking service, the parameter to skip tracking is set to true by default.

Added dotenv support

This release adds support for passing a dotenv file name to the fastlane command (contribution by @fahrenkrug).
It also includes minor updates of dependencies.

Verbose option and documentation update

Removing Ruby version specification

This version removes the problematic, hardcoded Ruby version specification. That requires the developers that use the action to precede the fastlane step with a setup-ruby step. More details about how to migrate to this version can be found in the README.

Fix for critical issue

The release contains a bug fix for a file permission issue that broke builds.

Fix for critical issue
