Target languages from Crowdin introduce some formating errors

[magul]

Issue description

Exporting languages from Crowdin contains formatting errors. There were first spotted in #1539

In source language we have there

<!--sec data-title="Chromebook setup (if you're using one)"
data-id="chromebook_setup" data-collapse=true ces-->
{% include "/chromebook_setup/instructions.md" %}
<!--endsec-->

which is not translated by Crowdin and unfortunatelly target langueges containes different formatting there:

<!--sec data-title="Chromebook setup (if you're using one)"
data-id="chromebook_setup" data-collapse=true ces--> {% include "/chromebook_setup/instructions.md" %} 

<!--endsec-->

Language

All languages exported from Crowdin.

Operating system

All.

Has this been brought up with the Crowdin staff? They might be able to do something about that. (E.g. introduce a GitBook-flavoured variant of MarkDown as new format.)

Not yet, was on weekend city break so with limited access to network. Do you want to push that topic there? I doubt that it could be solved somehow, as we're using pretty low level, raw formatting here:

<!--sec data-title="Chromebook setup (if you're using one)"
data-id="chromebook_setup" data-collapse=true ces-->
{% include "/chromebook_setup/instructions.md" %}
<!--endsec-->

Also worth fixing is translation of data-title (as it's not visible there at all).

Actually, I knew that there was a plan to abandon that <!--sec... solution. I found #1173, maybe we should move toward that direction? These {% ... %} should be properly rendered on Crowdin, should be translatable and should render in targeted languages properly.
