Fixed integration testing with random product names (#1074)

In the latest update to the `ucx` framework, the `trigger` function in
`tasks.py` has been modified to include a new argument,
`install_folder`, in the `Installation` object. This object is now
created within the `trigger` function and is passed to the `run_task`
function. The `install_folder` is calculated by obtaining the parent
directory of the `config_path` variable, converting it to a POSIX-style
path, and removing the leading "/Workspace" prefix. This change ensures
that the `run_task` function receives the correct installation folder
for the `ucx` framework, enhancing the overall functionality and
accuracy of the `ucx` framework.
