Update translation.md

Table sorted alphabetically as commented on this thread.

Changes as part of this PR:

• Reorder table alphabetically
• Match upper/lower case
• Fix minor typo (ámbito)
• Leave all terms in lower case unless proper noun

When a word in English is not translated (e.g. key), it is wrapped in underscores to make it show in italics on preview. But there are some words that don't follow this pattern:

• issue
• layout
• push (from "notificaciones push")
• script
• stub

I see how push and script may not needed as they are common in Spanish too, but should the other 3 be updated to _issue_, _layout_, and _stub_ respectively?

Thanks for the changes @alvaromontoro.

About the cursive words, I would go for adding all words that are not adapted to spanish in cursive (it's the common use case in spanish language). In my opinion, then all of them push, script, layout, stub included.

@xmartinezpujol I made those changes to display them on cursive.
