Added translations to codemirror-search

[SundeepChand]

Fixes #1588

I have verified that this pull request:

• has no linting errors (npm run lint)
• is from a uniquely-named feature branch and has been rebased on top of the latest master. (If I was asked to make more changes, I have made sure to rebase onto master then too)
• is descriptively named and links to an issue number, i.e. Fixes #123

I have tried to pass the translations by directly importing the i18n into codemirror-search.js. Please check this out (I have added translation for find on line no 238) & let me know if this approach is fine. If its fine, then I will update rest of the words.

Thanks for working on this! I think there's some missing translations here:

• The input placeholder "Find in files" is not translated
• None of the ARIA labels are translated (the search options, Next, Previous, and Close).

@catarak Sorry, have not had time to test it myself, but I think that @SundeepChand only want to test if the i8n t translation function works testing just one label, and if it works then an additional PR could be created.

Thank you for reading this PR more closely than me 😄 you are right!

Thanks @oruburos, I had meant this only. By the way, @catarak I have changed all the labels now. Please check this out. And please verify the Spanish words as well.
