title: How to reference yaml variable file present in github in robot framework test case file in github
body: <p>I ran Robot framework test cases(present in github) through azure pipeline. Test cases executed fine. Next I modified robot framework test case file to import yaml variable file (variable yaml file also present in same github repo folder) which has variables to be used by test cases file.
  yaml variable file looks like this</p>
  <pre><code>login:
   url: xxx.com
   email: abc@y.com 
   password: xyz
  </code></pre>
  <p>And my test cases file look like this</p>
  <pre><code>*** Settings ***
      Library           SeleniumLibrary
      Variables         variablesfile.yaml
    
    *** Test Cases ***
    Dev_TC01_AddProcess
    Open Browser    ${login.url}    chrome
    Input Text    id=email    ${login.email}
    Input Password    id=password    ${login.password}
  </code></pre>
  <p>And my yaml pipeline to trigger test scenarios looks like this</p>
  <pre><code>- script: |
      pip install pytest pytest-azurepipelines
      pytest
      robot --pythonpath . -x outputxunit.xml TestScenarios.robot
    displayName: 'Run Robot Scripts'
  </code></pre>
  <p>but on running the pipeline I get error, because test scenarios file is unable to reference variablesfile.yaml. got error message - Resolving variable '${login.url}' failed:</p>
  <p>Can you please suggest how to reference variable file</p>
