sf auth web login command for non-preview sandbox generates json file `~/.sfdx/username@as.email.json` with preview API version "63.0" which produces many different errors

Start by reproducing the problem with sf auth web login against a non-preview sandbox, then inspect the generated ~/.sfdx/username@as.email.json and compare its instanceApiVersion with the sandbox. Verify the result using sf org open and sf bulk data upsert, including their --json variants; done means these commands no longer fail because of an unavailable preview API version.

Note
Before you submit your issue, make sure that:

• You're using the latest version of Salesforce CLI.
• You've searched both open and closed issues for related posts.
• You've used the doctor command to diagnose common issues.
• You understand that GitHub Issues don't adhere to any agreement or SLA.
  • If you require immediate assistance, use official channels such as Salesforce Customer Support.

• Provide detailed step-by-step instructions on how to reproduce the issue.

1. Create a non-preview sandbox.
2. Authorize it using sf auth web login command
3. Notice instanceApiVersion has preview version 63.0.
4. if you try to execute sf org open you will receive an error with no description
5. If you try to execute sf org open --json there will be 404 not found errors probably because version 63.0 is not available for non-preview sandbox and any requests there fail as not found.
6. Same for sf bulk data upsert
