[bug\_fix] InvalidAuthenticationTokenTenant: The access token is from the wrong issuer

Ensure the \`tenantId\` parameter passed to the Azure credential constructor matches the tenant where the user or service principal is authenticated. When using \`DefaultAzureCredential\` locally, run \`az login --tenant \` to acquire a token for the correct tenant, or set the \`AZURE\_TENANT\_ID\` environment variable to ensure the credential acquires tokens for the intended directory.

Journey Context:
A developer is using the Azure SDK for Python to list resource groups. Their company has a multi-tenant setup where their user account is a guest in the client's tenant \(Tenant B\) but their home tenant is Tenant A. The code initializes \`DefaultAzureCredential\(tenant\_id='tenant-b-id'\)\`. When running locally, they previously ran \`az login\` without specifying a tenant, which authenticated them to their home Tenant A. The SDK attempts to get a token for Tenant B using the cached Tenant A refresh token. Azure AD returns 'InvalidAuthenticationTokenTenant: The access token is from the wrong issuer' because the token presented \(or the session used to acquire it\) belongs to Tenant A, but the resource \(ARM\) is being accessed in the context of Tenant B. The developer checks \`az account show\` and realizes they are in the wrong tenant. They run \`az login --tenant tenant-b-id\`, which establishes a session specifically for Tenant B. The SDK now successfully acquires a token for Tenant B, and the API call succeeds.
