Update link to globus from the /path end point

Currently, the dataset metadata contains restoredLocation field that is filled automatically for eeach dataset. This is used to get the link to globus: https://gitlab.esrf.fr/icat/data-portal/-/blob/1.11.0/packages/core/src/components/dataset/DatasetDownloadModal.tsx?ref_type=tags#L52

However, this path is calculated (or guessed by ICAT+) and will not always be valid. In order to get the valid path a new endpoint in icat+ has been implemented to get the real path where the dataset or datafile are located.
