fix(theme): update to remove deprecation warning

[jmfrancois]

What is the problem this PR is trying to solve?

Following the update of sass compiler we now have lots of deprecation warning.

Bootstrap has a pull request 1218 to fix that.
We have released this PR under @talend/bootstrap-sass.
we should may be add it in the mono repository for maintainance purpose but for testing purpose I have pushed a fork here which is a fork of this PR integrated.

Because our theme is an overide of bootstrap-sass we have also fix to provide.

What is the chosen solution to this problem?

Provide fix and integrate @talend/bootstrap-sass.
No more deprecation warning in our build logs.

Bonus: fix postcss configuration
