Labels refactor, resource routes & testing frameworks

[jamiefeiss]

Replaced profile-driven label predicates with the list of annotation predicates retrieved from the root API endpoint, as in RDFLib/prez#164. Labels, descriptions & provenance are now retrieved using getAnnotation() and the convenience functions getLabel(), getDescription() & getProvenance().

Also refactored the types & props for PropTable.vue and its children components following the annotation predicates refactor.

Updated the routes for dcat:Resources in CatPrez to use the following routes:

• /c/catalogs/<catalog_curie>/resources
• /c/catalogs/<catalog_curie>/resources/<resource_curie>

Added some initial unit, component & end-to-end tests as well as benchmarking using the Vitest & Cypress testing frameworks.

Resolves #115.

Haven't had a look at the test parts yet - visually checked the functionality and it looks fine.
If a link is not available for a resource it means there is no class information for it. At present the UI provides a link to the current page - which is probably not expected. We should have a think about what to do in this scenario - might be best to consider it incomplete data for the resource and not return it in the listing in the first place.

Tested it locally with the ANU instance of catprez and it looks good!
