go.sum is present in the repo and in .gitignore

[adrianlzt]

This commit added go.sum to the .gitignore file (2021/2/1). @hunchback error?

The go.sum file was deleted here by @lebauce (2019/11/12) and added back here by @amorenoz (2021/07/15).

So, with or without?

[lebauce]

Theoretically, go.sum should be part of this repository but I still having troubles understanding why the content differs from one machine to an other, causing the go-fmt test to fail so I ended up removing it. Now that Go modules are a bit more stable, we should probably add it back

[lebauce]

This is now fixed. go.sum is tracked by Git and removed from .gitignore
