Instructions incorrect for "Add the Vault Docker lab Certificate Authority certificate to your operating system trust store."

[hashimara]

Someone incorrectly did a find-and-replace in the example commands for adding the Vault Docker lab Certificate Authority certificate. This mistake is replicated across all examples under step #3. The container directory name is incorrect. It currently reads "Vault Docker lab_node_1" when it should read "vdl_node_1". So, for the macOS example, the following command doesn't work and will lead to launch failure:

sudo security add-trusted-cert -d -r trustAsRoot
-k /Library/Keychains/System.keychain
./containers/Vault Docker lab_node_1/certs/vault_docker_lab_ca.pem

Instead, it should read--

sudo security add-trusted-cert -d -r trustAsRoot
-k /Library/Keychains/System.keychain
./containers/vdl_node_1/certs/vault_docker_lab_ca.pem

Please make the corrections in README across all OS examples in step #3, so that new users of this repo can successfully launch clusters.
