Feat: allow logcat attachment to be previewed in Sentry

[bricefriha]

Context

As issue #3703 reports, Logcats files currently attached to Sentry issues are not previewable.

This issue is due to the mime-type sent with the file, as it currently has its own type, text/logcat. However, Sentry's preview component does not support this type.
This PR aims to tackle just that by changing the mime-type we send from text/logcat to text/plain.

Caviat

I personally believe that the user should have a more console-like experience when looking at the preview on Sentry. To tackle this, an issue in Sentry's repo is currently open. So, the PR would offer more of a temporary fix than a complete solution.
Therefore, when/if text/logcat gets support, we could change the mime-type back on our end

I can't find a way to get mime-type during device tests.

But it's not like we need to test this since the mime-type been hardcoded anyways

@bricefriha the device tests are just unit tests that get run on Android or iOS by our device runner here:

sentry-dotnet/test/Sentry.Maui.Device.TestApp/Startup.cs

Lines 22 to 29 in a2bdc82

	conf.AddTestAssemblies([
	typeof(Sentry.Tests.SentrySdkTests).Assembly,
	typeof(Sentry.Extensions.Logging.Tests.LogLevelExtensionsTests).Assembly,
	typeof(Sentry.Maui.Tests.SentryMauiOptionsTests).Assembly,
	#if ANDROID
	typeof(Sentry.Android.AssemblyReader.Tests.AndroidAssemblyReaderTests).Assembly,
	#endif
	]);

So you don't need to do anything special... just write some unit tests for LogCatAttachmentEventProcessor.Process.

Note: I see that method isn't very testable... it references static methods like OperatingSystem.IsAndroidVersionAtLeast so it might need to be refactored a bit.

Looks good - thanks @bricefriha !

Just one question - have you actually tested this in an android app to make sure the logs come through OK and can be previewed in Sentry?

@jamescrosswell I have tested with the sample we have and it can be previewed in Sentry (as you can see on the screenshot in the description)
