Tracking flaky tests

Related to the #1680 epic I wanted to create an issue to start actually tracking some of the tests that I'm continually seeing failing. As I notice them I'll start listing them in here and then will try to address them one the build has been cleaned up fully.

bloop.scalajs.ScalaJsToolchainSpec seems to be failing often in the platform bridges
bloop.dap.DebugServerSpec seems to be failing pretty often.
bloop.launcher.LatestMainLauncherSpec also seems to be failing often. The weird thing is that it seems to be failing on the check if python is there. There is a timeout of 2 second, so maybe we try to bump that up, but that seems odd to be failing.
bloop.dap.DebugProtocolSpec

referring to the python check up above

bloop/bloopgun/src/main/scala/bloop/bloopgun/core/Shell.scala

Lines 214 to 218 in 5406395

    
             def isPythonInClasspath: Boolean = { 
        
               if (!detectPython) false 
        
               else runCommand(List("python", "--help"), Environment.cwd, Some(2)).isOk 
        
             } 
        
           }

I think the problem with the tests is that they assume strict timings, so it's easy for the to be flaky 🤔

I've been trying to fix them, but I haven't been able to make too much of a dent here.

	def isPythonInClasspath: Boolean = {
	if (!detectPython) false
	else runCommand(List("python", "--help"), Environment.cwd, Some(2)).isOk
	}
	}
