Fix dispatch API path

[slester]

Description

As per the API documentation, the path should have /dispatch when deploying to the namespaced dispatch API.

Otherwise, we had the following error:

error uploading worker '123-456-abcdefghi': PUT method not allowed for the api_token authentication scheme (10000)

Upon adding /dispatch into the URL, we got successful responses.
