codecov: fix `after_n_builds` to 5
Created by: unknwon
On almost all PRs, we only have 5 reports/uploads, e.g. https://codecov.io/gh/sourcegraph/sourcegraph/commit/ffe90713033a6483f8137ca3eab64f556ebed5ab/build
If we include e2e, then we have 6 but that doesn't run on most PRs (almost always only on master
?). Therefore, if we set after_n_builds
to 6, PRs are no longer receiving PR comments from Codecov.
