Automated VIC UI Plugin - Update drone trigger

[ghost]

User Statement:
As a developer I want automated testing of the automated VIC UI plugin install.

Details:

Acceptance Criteria:

• Update vic-ui downstream triggers to vic-product instead of vic

[zjs]

@wjun: This should be an easy change to update the DOWNSTREAM_REPO variable in the .drone.yml:

vic-ui/.drone.yml
