📜 Reorganize Weblate components

[AnneliesVlaar]

The following changes are needed:

• the Weblate components for parsons, tutorials and cheatsheets should be removed because these features will be deleted soon.
• the workbooks, which are currently in the pages component, need to be extracted in a separate component. The workbooks component should be permanently locked until the workbooks feature becomes publicly available.

As discussed on Discord with @Felienne and @boryanagoncharenko when the workbooks are in their own file/folder, let's lock the workbook content on weblate until they are finished/ready for publishing
