fix: provide blockId to uploadFile in UploadTab (#1641)

* refactor(core): rename block to blockId
Rename the input of editor.uploadFile to make it clearer that it is a string that is manipulated and to make it coherent with the above function definition

* feat(file-panel): add blockId parameter to the call of editor.uploadFile
