Documentation: wrong command to deploy versioned artifact to DataHub

[bda618]

Describe the bug
Readme.md at metadata-models-custom is referencing to the below command

../gradlew -PprojVersion=0.0.1 install

to deploy your versioned artifact and "unpack the artifact and deposit it under ~/.datahub/plugins/models/<registry-name>/<registry-version>/."

However, the versioned artifact is not getting deployed. There is no any error or warnings.

To Reproduce
Follow "Deploy your versioned artifact to DataHub" instruction at Readme.md of metadata-models-custom

Expected behavior
This will unpack the artifact and deposit it under ~/.datahub/plugins/models/<registry-name>/<registry-version>/.
