utils/build-galaxy-release.sh: Add "-i" to install generated collection

The "-i" option can be used to install the generated collection using
the ansible-galaxy collection install command. It is using the force
flag to install the collection if there is already a collection with the
same name and namespace. The ansible-galaxy collection build command is
already using the force flag to create the collection.
