GameLift Export Script Non-Actionable Seed Warning

[AMZN-Gene]

If a game is missing seed files, the exporter will tell the user that it's missing the files, but not provide anything actionable to try in order to fix the issue

Steps to reproduce Steps to reproduce the behavior:

1. Delete the seed files in .\AssetBundling\SeedLists
2. Run the exporter D:\GitRepos\O3DE\o3de\scripts\o3de.bat export-project -es D:\GitRepos\O3DE\o3de-multiplayersample\MPSGameLift\Scripts\export_gamelift_server_package.py --code --assets -ll INFO

Expected behavior A clear message that seed files are missing and how developers need to provide seed files and a link to online documentation about seeds

Actual behavior There's an error but no action item [ERROR] root: Building assets failed! Could not find any game seed files inside D:\GitRepos\O3DE\o3de-multiplayersample\AssetBundling\SeedLists

Found in Branch development

Can we provide general seed as a default for all of the levels in your project? this will be scary for new people who then need to go watch another series of tutorials on how to build seeds.
