Stop collecting test coverage on CI

CI collected coverage data from the unit and integration tests only for
the Codacy upload. Nothing else reads it.

Remove the coverage flags, the LAZYGIT_GOCOVERDIR env var and the
artifact uploads from the CI workflow. Keep the support for
LAZYGIT_GOCOVERDIR in run_integration_tests.sh and in the integration
test runner, so that we can still measure the coverage of the
integration tests locally.

Remove the step in run_integration_tests.sh that merges the coverage
files, though. It only existed to reduce the number of artifacts to
upload.
