Pre Request vars in request not getting proper value when using bru cli

[yellow-straw-hat]

I have checked the following:

• I use the newest version of bruno.
• I've searched existing issues and found nothing related to my issue.

Describe the bug

Bruno cli seems to not using the defined variable :

vars:pre-request {
  base64_encoded_file: aGVsbG8gd29ybGQ=
}

So when calling the variable in the request body, it will always be empty

This tag (vars:pre-request) does not exist in your documentation here : https://docs.usebruno.com/bru-lang/tag-reference

.bru file to reproduce the bug

Upload file:

meta {
  name: Upload Files
  type: http
  seq: 10
}

post {
  url: http://localhost:8080/v1/file
  body: json
  auth: none
}

body:json {
  [
    {
      "contents": "{{base64_encoded_file}}"
    }
  ]
}

vars:pre-request {
  base64_encoded_file: aGVsbG8gd29ybGQ=
}

assert {
  res.status: eq 201
}

tests {
  test("should return 201 http status code", function() {
    expect(res.getStatus()).to.equal(201);
  });
}

Running with:

docker run \
  --rm --volume .:/tests \
  --workdir /tests bruno-cli:latest run

Note that this request is working with Bruno Desktop App.
