Fix: Zoomus cannot be installed latest version.

[ghost]

General troubleshooting steps

• [x] I understand that if I ignore these instructions, my issue may be closed without review.
• [x] I have retried my command with --force.
• [x] I ran brew update-reset && brew update and retried my command.
• [x] I ran brew doctor, fixed as many issues as possible and retried my command.
• [x] I have checked the instructions for reporting bugs.
• [x] I made doubly sure this is not a checksum does not match error.

Description of issue

Latest Zoomus cannot be downloaded.

It is because Zoomus download link now redirects to cloudfront URL, and it adds unnecessary query to URL, so filename under Caches/Homebrew/downloads and symlink under Caches/Homebrew/Cask doesn't match with the name Zoom.pkg.

To fix it, I approach the below steps.

1. Fix Homebrew/cask/installer.rb to ignore query if URL has query. This is big changing so I skipped.

2. Fix homebrew-cask/Casks/zoomus.rb url as https://d11yldzmag5yn.cloudfront.net/prod/#{version}/Zoom.pkg. I made a branch and this works fine and passed all test.

Therefore, I think it needs to fix like Step 2 above, but I wonder if the url was verified as official when first introduced to the cask. Could you tell me how to make sure?

I checked URLs in old commits, and they all seem to redirect to d11yldzmag5yn.cloudfront.net, so fine.

When it's confirmed, I will send PR.

Command that failed

Therefore, I think it needs to fix like Step 2 above, but I wonder if the url was verified as official when first introduced to the cask. Could you tell me how to make sure?

You submit it and a maintainer will verify it. I just did and it seems fine.

When it's confirmed, I will send PR.

If you already have a PR, don’t ask for permission to submit, just do and we’ll discuss it there. It saves time and allows for better discussion.
