Remove unnecessary CA2022 suppressions

[NikolaMilosavljevic]

As part of re-bootstrapping in dotnet/installer#19145 we've encountered numerous CA2022 errors. This required patches for several repos. Most of those changes were backported.

It appears that compiler/analyzer was unnecessarily restrictive and the change was made in dotnet/roslyn-analyzers#7268 to relax the check.

Once we pick up newer SDK (9.0.100-preview.4.24209.7 or later) we should be able to remove all of these suppressions and backport them.

I couldn't figure out the best area label to add to this issue. If you have write-permissions please help me learn by adding exactly one area label.

[Triage] Is there anymore work to do here? The last patches are being removed in dotnet/installer#19508.

This issue tracks removal of suppressions that were added with dotnet/installer#19145

Analyzer was too restrictive - it was fixed with dotnet/roslyn-analyzers#7268

This work can be done after next VMR re-bootstrapping.
