🪲 [Fix]: Fix conditional logic for test result handling (#92)

## Description

This pull request includes a small change to the `scripts/main.ps1`
file. The change modifies the conditional logic to use an `elseif`
statement instead of a separate `if` statement, ensuring that the script
correctly handles the cases where tests have failed or all tests have
passed.
