k6 cloud login stack trailing `/`

[ankur22]

Brief summary

k6 cloud login fails when the stack is provided with a /:

k6 cloud login

         /\      Grafana   /‾‾/  
    /\  /  \     |\  __   /  /   
   /  \/    \    | |/ /  /   ‾‾\ 
  /          \   |   (  |  (‾)  |
 / __________ \  |_|\_\  \_____/ 

Enter your token to authenticate with Grafana Cloud.
Please, consult the documentation for instructions on how to generate one:

  Token: 

Enter the stack where you want to run k6's commands by default.
You can enter a full URL (e.g. https://my-team.grafana.net) or just the slug (e.g. my-team):

  Stack: https://foobar.grafana.net/
ERRO[0010] Authentication failed as provided token or stack might not be valid. Learn more: https://grafana.com/docs/grafana-cloud/testing/k6/author-run/tokens-and-cli-authentication. Server error for details: (403/error) Stack not found or you don't have access: 'https://foobar.grafana.net/' 
exit status 255

If the trailing / is removed the login works:

k6 cloud login

         /\      Grafana   /‾‾/  
    /\  /  \     |\  __   /  /   
   /  \/    \    | |/ /  /   ‾‾\
