add --hide-traces flag to deno test to ignore the stack trace completely

[carafelix]

I been using deno test in the simple describe > it fashion, and it's alright. The only downside I've encounter is when multiple test's are failing, it gets cluttered real quickly with long stack traces. When writing good describe-it combinations I already now where and what failed, so it's not necessary that whole stack trace. Adding -q flag won't help it.
Current:

describe it description yara yara
error: AssertionError: Values are not equal.


    [Diff] Actual / Expected


-   undefined
+   "poussar"                   <-- up to here would be okay some times :) 

  throw new AssertionError(message);

#13586 and #14921 mention shortening the stack trace. I would like a flag to completely remove it.
Desired:

describe it description yara yara
error: AssertionError: Values are not equal.

Call it --hide-traces or --hide-stack-trace or whatever you wanna call it, but as of rn its too much visual noise. Thanks
