CLI 'fix' doesn't cover diagnostics that 'analyze' does

I ran `analyze` for CS8600 and got a list of warnings, then simply changed `analyze` to `fix` and it neither reported the warnings nor changed the code. I was using diagnostic verbosity as instructed by the 'fix --diagnostic-fixer-map' documentation, "Set verbosity to 'diagnostic' to see which diagnostics cannot be fixed due to multiple fixers." I also tried including a few other args like `--diagnostics-fixable-one-by-one "CS8600"`, `--diagnostic-fix-map "CS8600="`, and `WorkdaySOAP.csproj`, but those attempts resulted in no difference in the output.

Compare these in a diff tool:

Using CLI version 0.11.0.0 that I just installed via `dotnet tool install -g roslynator.dotnet.cli` on Windows 11.

Start with the roslynator analyze and fix CLI entry points and the --diagnostic-fixer-map documentation, then reproduce the report using --supported-diagnostics CS8600 --verbosity diagnostic against WorkdaySOAP.csproj. Done means the fix command accounts for the diagnostics reported by analyze, or the unsupported case is clearly identified in the CLI behavior or documentation.
