feat!: update target frameworks to net8.0 and net10.0, drop net5.0 (#3096)

* feat!: update target frameworks to net8.0 and net10.0, drop net5.0

BREAKING CHANGE: Dropped net5.0 target framework. The SDK now targets
netstandard2.0, netstandard2.1, net8.0, and net10.0. Consumers targeting
net5.0 must upgrade to net8.0 or later.

- Update Microsoft.Graph TFMs from netstandard2.0;netstandard2.1;net5.0
  to netstandard2.0;netstandard2.1;net8.0;net10.0
- Update test project from net8.0 to net8.0;net10.0
- Replace net5.0 per-TFM property groups with net8.0 and net10.0

Fixes #3095

* refactor: consolidate per-TFM property groups into global NoWarn

Remove redundant per-TFM DocumentationFile/NoWarn property groups that
could cause parallel build file write races. GenerateDocumentationFile
is already enabled globally, and NoWarn values are now consolidated into
the main PropertyGroup.
