This PR fixes #94285

What:

Based on the problem described on #94285; I've added a new set of configurable options that are under the task configuration. This option is saveBeforeRun: <always|never|prompt>; defaulting to the first option of always saving before running a task (current behavior).

How to test:

Include on settings.json:

• "task.saveBeforeRun": "never":
  Execute a task, with this option selected, the editor will not save the dirty editors and run the selected task.

• "task.saveBeforeRun": "prompt":
  Execute a task, with this option selected, the editor will ask you if you want to either save or not save all editors.

• "task.saveBeforeRun": "always":
  Execute a task, with this option selected, the editor will behave as of now, all dirty editors will be saved and the task will be run.
