Say hello to v13.1.0 - Now with javascript bookmarks support

[marcelklehr]

Hello everyone,

v13.1.0 just hit release and comes with support for javascript bookmarks now. As a security measurement, existing client applications that interact with the Bookmarks App REST API will have to opt into this new feature by using the new target field instead of the traditional url field when using bookmark structs recevied from the API. You can find more details in the docs at https://nextcloud-bookmarks.readthedocs.io
