Re-enable codecov

[etr]

Identify the Bug

Codecov succeeds the execution but fails to handle the coverage files once pushed.

Description of the Change

This seems due to the library building on a separate path. The default codecov script uses the project base root as a starting point so the relative paths don't work.

This change attempts to fix the issue by disabling the standard directory rewrite used by codecov.

Alternate Designs

We could just build in the same directory in a separate build for codecov.

Possible Drawbacks

None

Verification Process

Github actions will execute the codecov action as part of the build.

Release Notes

Re-Enable automated code coverage calculation.
