Generate URL to directly access generic package asset list
When uploading (or even downloading) assets using the API, we can use the following descriptive URL:
${CI_API_V4_URL}/projects/${CI_PROJECT_ID}/packages/generic/${_subgroup}/${CI_COMMIT_TAG#v}/${_file_name}
When trying to access the 'list' of packages however, we cannot use
${CI_API_V4_URL}/projects/${CI_PROJECT_ID}/packages/generic/${_subgroup}/${CI_COMMIT_TAG#v}
nor even
${CI_API_V4_URL}/projects/${CI_PROJECT_ID}/packages/generic/${_subgroup}
but instead have to use
https://gitlab.com/${PROJ_PATH}/-/packages/22250420
where the ID is 'unknown' beforehand. It is an internally randomly generated ID.
Instead, it would be nice, that in addition to the above, we have a more permanent, predictable and logical path to get the the generic packages pages, so we can programmatically access them.
