Update 'Severity' section in Option Format

Type of issue

Outdated article

Description

See dotnet/roslyn#52991. Before dotnet/roslyn#69844 got merged, the severity specified in option_name = option_value:severity was only respected in the IDE live analysis, not on command line builds. The documentation correctly mentions this information.

However, with the above change, the severity specified in option_name = option_value:severity will get respected on build as well. Note that to prevent any breaking changes, this functionality is not enabled by default, unless the AnalysisLevel or AnalysisLevelStyle is greater than or equals 9.0 or set to preview on .NET 8 SDK and also in the future when we release .NET 9 SDK and users migrate their project to net9 without setting any AnalysisLevel value - for net9 TFM we would default AnalysisLevel to 9.0 and hence this feature will get turned on by default.
