Document .NET mobile support

[bruno-garcia]

SDK

.NET SDK

Description

Stuff like options.Native. are undocumented. We have samples e.g:
https://github.com/getsentry/sentry-dotnet/blob/d179ec9157934e9fbaa0e00860e6c1e090029414/samples/Sentry.Samples.Ios/AppDelegate.cs#L25

But we need these in the docs.

MAUI vs native .NET is also not documented.

Symbol upload has no reference to the fact it can upload native symbols, proguard.

Suggested Solution

.NET mobile is growing a lot, document it's capabilities so folks looking to set things up have all the tools they need.
Have the concept of platform/OS more clear on the docs, calling out that Sentry for .NET works on Windows, macOS, Linux, Android, iOS and WebAssembly. And that we have native support through Native AOT as well as everything our native mobile SDKs suppot.
