OpenFGA JS SDK v0.2.6 is out with various fixes

[rhamzeh]

We've just released v0.2.6 of the OpenFGA JS SDK

The highlights of this release include:

• Credentials: Retry on errors when performing the client credentials flow, so that temporary 429 or 5xx issues with your token issuer do not block you
• Client: ListRelations, BatchCheck and non transactional Writes, will attempt to validate the connection to the API
• Validation: If you mistakenly put in a dummy value not in the ulid format in the StoreId or AuthorizationModel ID in the Client, it will now warn you
