[New Feature] provide version information of Bruno in JavaScript

[tho-gru-38]

I have checked the following:

• I've searched existing issues and found nothing related to my issue.

Describe the feature you want to add

I want to make sure, that my collection is executed by a specific version of Bruno. Currently I want version 1.35.0 because this versions handle line comments correctly (issue #3216 is solved by this version).

I want to implement a test like to stop collection execution using bru.setNextRequest(null) if the version of Bruno does not fulfill the requirements.

My idea is that a new function like bru.getVersion() will return a string like "1.34.2" for Bruno version 1.34.2

With such a function the follwoing code can check if the minimum required version is used for executing a collection.

Mockups or Images of the feature

The following checks the version of Bruno and aborts collection run if Bruno is not at least version 1.34.2:

const minVersion = "1.34.2";
let versionOK;

test("Bruno version is ok", function () {
  versionOK = false;
  const currentVersionComponents = bru.getVersion().split(".");
  const requiredVersionComponents = minVersion.split(".");
  for (let i = 0; i < currentVersionComponents.length; i++) {
    expect(currentVersionComponents[i]).to.be.at.least(requiredVersionComponents[i]);
  }
  versionOK = true;
});

if (!versionOK) {
  test("abroting collection run", function() {
      throw new Error("Minimal version of Bruno must be at least " + minVersion);
    });
  bru.setNextRequest(null);
}
