feat(nextcloud)!: Support server 29 and spreed 19

[provokateurin]

Depends on nextcloud/server#44732
This is not the final version (I hope for nextcloud/spreed#12041 to land), but everything is working already when testing against the old versions. Once the server releases are done and the docker images are available we can also test against those and get this merged.

Everything merged upstream, this PR is ready :)

[Leptopoda]

So far LGTM
I've looked at every json spec and tried to pay special attention to oneOf and anyOf. I could not find any obvious issue.

[provokateurin]

@Leptopoda please review the maxItems fix. I think there is something fundamentally wrong about checks for types in someOfs because they don't get generated anywhere, but that was already the case before and is not in scope of this fix.

[Leptopoda]

I think there is something fundamentally wrong about checks for types in someOfs because they don't get generated anywhere

Can you show me where you'd expect one but they are not generated?

[provokateurin]

For example https://github.com/nextcloud/neon/blob/007a96fa4334433ac35e00fc0d794fd015184f3b/packages/nextcloud/lib/src/api/spreed.openapi.dart#L16365C9-L16365C25 should have the check but I don't see it anywhere.

[Leptopoda]

I see. The only validation it uses is through the use of Never.
I think a proper validation will come once we convert someofs back to normal objects (#1508).

[provokateurin]

Yeah, no point in spending time on fixing this right now.

[provokateurin]

@Leptopoda can you review again?

[Leptopoda]

looks good for now.
I have a lot of dynamite changes coming so I'll do a final review once it is ready to be merged
