feat(runtime): Making --prompt the default behavior instead of throwing error

[getspooky]

Like browser permission experience, it would be more useful to include permission prompt by default instead of throwing error.

Please See Discussion: #10183

Example:

const json = fetch("https://api.github.com/users/denoland");

json
  .then((response) => {
    return response.json();
  })
  .then((jsonData) => {
    console.log(jsonData);
  });

deno run example.ts

Result:

⚠️  ️Deno requests net access to "api.github.com". Allow? [y/n (y = yes allow, n = no deny)]

Implementation is completely wrong: the goal is to make it the default behavior, aka having a no-prompt flag that allows it be disabled. Also this most definitively should not be done pre 2.0

Thanks for opening the PR @getspooky but it's hasn't been yet agreed upon that we want to proceed with --prompt by default. Additionally there's quite a lot of auxiliary logic that will need to be implemented for this feature (eg. detecting if running in TTY). I'm going close it now, and let's drive discussion in #10183 home before implementing a PR.
