Some commands are deprecated and will be disabled soon #6

Hi Browserstack team,

I got some warnings when running the Github Actions:

Warning: The add-path command is deprecated and will be disabled soon. Please upgrade to using Environment Files. For more information see: https://github.blog/changelog/2020-10-01-github-actions-deprecating-set-env-and-add-path-commands/

Warning: The set-env command is deprecated and will be disabled soon. Please upgrade to using Environment Files. For more information see: https://github.blog/changelog/2020-10-01-github-actions-deprecating-set-env-and-add-path-commands/

Thanks for the fix! 😉
