 I managed to solve this and to be honest, I don't know why it worked but here the solution I found : 

When the system asks you to login with your Trailhead account, DO NOT USE the email field, click on SALESFORCE account instead (see screenshot). And then I was presented all my available Orgs !

正直、なぜうまくいったのかはわかりませんが、私が見つけた解決策は次のとおりです。 

システムから Trailhead アカウントでログインするように求められたら、メール フィールドを使用せず、代わりに SALESFORCE アカウントをクリックしてください (スクリーンショットを参照)。すると、利用可能なすべての組織が表示されました。

# We found at least one Salesforce account linked to your Trailblazer.me profile, but you don't have permission to install packages. Ask your admin to assign you the Manage Billing permission in the org where you want to install the package. You can also sign up for a free trial of Salesforce
