[BUG] Orb fails with older versions of `curl`

Describe the bug
When running this Orb on Ubuntu version 20.04 with an older version of curl, the download succeeds but the Orb fails to execute the last download step.

To Reproduce
Steps to reproduce the behavior:

1. Use an executor with the docker image of cimg/base:current-20.04

Expected behavior
The download and codecov CLI commands should succeed.

I believe the issue is with the last command that calls an API with curl and prints a version. This command could be removed or replaced with:

  # Get version from the downloaded binary instead of API                                                                                                                   
  v=$(codecov --version 2>&1 | awk -F', version ' '{print $2}' || echo "unknown")    

Regression
The extra curl option of --retry-all-errors was added in version 5 of this Orb.

Additional context
Add any other context about the problem here.

Start with src/dist/download.sh at the linked lines 94-96 and reproduce the failure using cimg/base:current-20.04 with an older curl. Compare the final download/version step with the issue's proposed local version lookup. Done means the download and codecov CLI commands succeed on that Ubuntu 20.04 image.
