Attempt at updating to .Net 10 to fix crash with OpenAPI

[duckblaster]

This breaks the tests using MySQL, as Pomelo.EntityFrameworkCore.MySql doesn't support EF Core 10, and has a few mysterious failures in the AzureSqlEntityTableRepository_Tests where the time is off slightly (rerunning the tests they passed on the second try).

Other than that, it seems to pass all tests.

I wanted to do the same @duckblaster. Thanks for tackling this. Every .NET Switch requires at least a couple of months of wait time until all libraries catch up :)
I guess we will have to wait for all packages with all dependencies to get to .NET 10 before we migrate and that'll probably happen when it'll be a time for .NET 11 release haha :D

Any chance we can get this merged? When Pomelo.EntityFrameworkCore.MySql catches up the only change will be to re-enable the tests using it.

I have also expanded the OpenAPI output to include the entity schemas instead of just reporting object.
OpenAPI output should now mostly match Swashbuckle, although there were a few more definitions in the OpenAPI doc already.

Sorry - I've been moving, and only just got my PC working again.

I'll be working on the dotnet 10 migration this weekend. There are a few things that need refactoring for dotnet 10 improvements, but I'll take a look at this PR during the weekend.
