NC 35 compatibility

[tflidd]

NC 35 will soon be released and currently there is no officially supported version of this app.

I didn't do any testing with the current version if it breaks, I will report back once I find some time.

I just updated appinfo/info.xml and set the nextcloud max-version to 35 and it appears to work. I only had to recreate my app passwords.
