Hebrew translation and RTL

Hi, I’ve translated the Other courses and Learn UI components to Hebrew via Crowdin.

Initially those projects were 1% or less when I started so I suggested several fixes to the former suggested strings.

Since Hebrew is written from Right-To-Left I have to make sure that the explanation parts are correctly aligned and that the code parts are correctly aligned the other way around (All <‎code> tags should be LTR regardless of content, I’ve added LRM to the problematic cases to make sure it’ll display correctly regardless of CSS directionality).

Thank you :slight_smile:
