Update Microsoft.Data.Sqlite.Core TFMs

[AndriySvyryd]

For .NET 11 we need to consider whether Microsoft.Data.Sqlite.Core should continue to support .NET Framework. And we should drop netstandard2.0 to avoid giving the impression that older TFMs like net8.0 are still supported. So, the final set would be one of:

• net10.0
• net10.0;net472
• net11.0;net10.0
• net11.0;net10.0;net472

@AndriySvyryd as per the discussion in https://github.com/dotnet/efcore/pull/35589/files#r1944379793, we also have the option of simply keeping netstandard2.0 and multitargeting to the minimum supported TFM (currently net8.0, for .NET 11 it will be net10.0).

Keeping netstandard2.0 will always result in the situation where an older TFM appears to be supported but suddenly loses DateOnly and TimeOnly support.

That's true - I'm just arguing that we shouldn't have that happened for supported TFMs (e.g. net8.0 currently). What happens to unsupported TFMs seems much less important.
