fix: evaluation of boolean conditions in github workflows

[Kevincifuentes]

📝 Description

This PR fixes the conditional for providing file name for diff-base-breakdown-file-name on the example provided, which was leading to always provide that value (even with thatmain.breakdown file is missing). The reason for this was that we were expecting a boolean output from the previous action and, unfortunately, even if the response is false, the conditional considers the value as string (already known behavior).

This PR simply checks that value as string and updates the documentation to display that change.
