Limit the visual impact of error squiggles lines and errors in minimap

[FALLAI-Denis]

Hi,

IBM Z Open Editor, or more specifically the Language Server, may have difficulty understanding the COBOL code of programs, even if that code compiles perfectly fine, in the case of certain COBOL copybook builds or when using the conditional compilation and evaluation of conditional compilation variable values.

We have implemented a solution that limits the visual impact of error squiggles and plays on the transparency of the red wave line, same thing for the rendering of the minimap:

  "workbench.colorCustomizations": {
    "editorError.foreground": "#ff000020",
    "minimap.errorHighlight": "#ff000020",
  },

The (false) errors are still there, but they no longer impact the readability of the code.

The change is global for all VS Code languages and editors.
