Correction of the issue 695

[florian714]

We have errors with the test svg : they are differents from the output svg and it fails the test. In this pull request, We changed how the axis name is displayed in order to fix #695. We could use some help with how to interpret and fix the test errors.

Can you demonstrate that you solved the problem ? Like by posting an example before and after ? (here or on the issue)

For the tests, you can run them on your own computer with testthat::test_local(). The 5 failing tests are all snapshot tests, i.e. tests that register a base image and then check that a code does not accidentally modify the output. This is normal here because your change does modify the output ! You can review and accept those changes locally with testthat::snapshot_review(). Do not blindly accept all changes : they actually help you check that only the needed parts have changed. Once you accepted a new snapshot you can commit it to this pull request as you would do for any other part of the code.

Here is a demonstration of the problem solved :
Before (ggstatplot main branch)

After (this branch, see the effectif properly displayed at the bottom of the image)

You can achieve the same results by cloning our branch and lauching the fixed ggstatbetweenplot function.
