[BUG] Action continues after download failing with "HTTP error"

Describe the bug
When the action fails to download https://cli.codecov.io/latest/linux/codecov because of "HTTP error", the rest of the action still proceeds.

To Reproduce
Steps to reproduce the behavior:

1. Use Github CI action
2. Have action fail to download CLI because of "HTTP Error"
3. See action progress despite not having downloaded the CLI required to continue.

Expected behavior
Failed download detected immediately and no attempt to verify the CLI integrity or running the upload-coverage command.

Regression
Not sure.

Additional context
None

Start with dist/codecov.sh, the entry point shown in the log, and trace the download step after the HTTP error. Done means a failed CLI download stops the action before integrity verification and upload-coverage; no test file is mentioned in the issue.
