When a new branch is created for a feature, it may not exist in the downstream repo. For example, during an exceptional minor release. In such scenarios, we fallback to the last known branch. This was previously handled in a catch block, but this change makes the fallback more explicit.

In some cases, such as when a new exceptional minor branch is created. The branch may not exist in the downstream repo. For example, during an exceptional minor release (e.g. FW 20.3.x and Components: 20.2.x).
This commit introduces a fallback mechanism to handle such scenarios. If the current branch is not found in the downstream repository, the script will now fall back to the last known branch from the build information. This ensures that the files can be updated properly.
