Docker NC21 collabora issue

Hi all, finally collabora folks resolved the problem. Many thanks!!

After update to collabora/code:6.4.10.10 documents load again!!

It looks the problem was here

some references to collabora forum (multiple user report it works with 6.4.10.6):

CODE 6.4.10_Docker - Nextcloud (Not working)

CODE connecting 0%: cannot connect to ods-document / stops working(https://forum.collaboraonline.com/t/code-connecting-0-cannot-connect-to-ods-document-stops-working/468)

CODE 6.4.10 - Well, this is embarrassing #2771
