Change .NET runtime targets to current recommendations

Solves #411.

These two warnings remain:

  NuGet.Build.Tasks.Pack.targets(221, 5): [NU5125] The 'licenseUrl' element will be deprecated. Consider using the 'license' element instead.
  NuGet.Build.Tasks.Pack.targets(221, 5): [NU5048] The 'PackageIconUrl'/'iconUrl' element is deprecated. Consider using the 'PackageIcon'/'icon' element instead. Learn more at https://aka.ms/deprecateIconUrl

I'm a little busy this weekend so I'm not sure when I can give this more thought, but we wanna be careful when touching Fsharp.Core:

Targeting an earlier version of FSharp.Core increases your reach because older codebases can use it without issue

I think it's reasonable to upgrade to 4.3.4, and I think that still solves #411, but haven't been able to thoroughly test it.

This build says

Passed! - Failed: 0, Passed: 153, Skipped: 0, Total: 153, Duration: 239 ms - Hedgehog.Linq.Tests.dll (net6.0)
but I only see 18 tests locally.

Why is that?

4.3.4 worked, so I used that.

I wasn't planning on getting this merged tonight, but my initial attempt to release version 0.13.0 failed. I had recently updated to the latest (fork) version of the NuGet publishing GitHub action. In hindsight, I should have not made that change until this code was merged. Of course I could have reverted that change, but who wants to go backwards in life? Not me.

Could it be the same tests are parameterized?

Yes, that it is. There are 18 tests, but one has 136 parameters, and 18 - 1 + 136 = 153.
