Describe the bug
The new Token Auth authentication method (added in #5080) is not correctly implemented.

To Reproduce

1. Try to use a (Cluster)SecretStore with these settings:

      auth:
        tokenAuthCredentials:
          accessToken:
            key: accessToken
            name: infisical-credentials
            namespace: external-secrets

2. The ClusterSecretStore is validated only once and then failed to be validated again
3. Check on your infisical account, the token has been revoked.

Expected behavior
The ClusterSecretStore must be validated and stable with Token Auth authentication method.

Additional context
I think the issue is due to the Close function of infisical provider (here).

func (p *Provider) Close(ctx context.Context) error {
	p.cancelSdkClient()
	err := p.sdkClient.Auth().RevokeAccessToken()
	metrics.ObserveAPICall(constants.ProviderName, revokeAccessToken, err)

	return err
}

It is a good practice to revoke the token for other auth methods but obviously not for Token Auth method.

I will provide soon a PR to solve the issue
