Calendar synchronization doesn't work because the url is too long

[Magikh42]

Describe the bug The calendar synchronization feature doesn't work with KOrganizer because the url is too long

To Reproduce Steps to reproduce the behavior:

1. Go to https://iintra.freekb.es/v2/options/calendar
2. Copy the ics file url
3. Open KOrganizer and add a new ics calendar

Expected behavior The remote calendar should be added

Desktop information (please complete the following information):

• OS: EndeavourOS
• Browser: Non-relevant
• Extension version: 4.4.2
• KOrganizer version: 6.5.3

Workaround Use a cron task to wcurl the file locally and configure KOrganizer to use the local file (wget doesn't seems to work with long urls, even when setting -O option to make the destination file path shorter)

Making the url shorter should fix this issue
