Codicon clutter in test explorer

[matter-it-does]

See the old and new comparison in https://github.com/microsoft/vscode-java-test/pull/1449

I'm used to seeing red and green in a list of over 200 tests and orange and violet disturb that quick scan.

Parameterized tests have been left out of the icon. (not that I want them, but just pointing out inconsistency)

Could you use the greyscale versions of these codicons ?

The icons are just added by a simple string. So, I'm afraid that there is no way to make it grey.

Maybe add a setting to control whether to show the codicon or not.

Meanwhile, I would like to see more feedback from users.

just me maybe.. I got used to it
