Remove English commented out code from translations

[XhmikosR]

It seems it's common practice. We need another way for translators to follow the English files and know up to where they have translated. Maybe a simple HTML comment with the hash and then they can compare after that and see the diff.

Right now, many translations follow this practice which results in ~2x lines. All this does not come for free and it's bloating the codebase IMO.

Also, there's #2450.

Hey! Can you tell me more about this issue?

EX: English text is copied into the translated documents like

https://github.com/nodejs/nodejs.org/blame/347682b75702a51d515b307aabd1e4766df55978/locale/ko/about/index.md#L9-L18

So if the English is updated, these are actually out of sync.

@XhmikosR and @nschonni, I know this so far, it seems this is Korean and Japanese's habit. So we don't need to worry about them.
But in order to be fair, I'd invite @nodejs/nodejs-ko and @nodejs/nodejs-ja to have a discussion about it. If they don't agree with your ideas, I have to close your issue.

Commenting the corresponding commit hash of English file may work. But transition will take time as it requires re-sync of all translation files. I personally don't have objections to having process transition. But I have to listen how @nodejs/nodejs-ko think.

It's also a habit in pt_BR, at least in some files.

We decided to go with CrowdIn approach here nodejs/i18n#72 and I'm now working on configuring it, so this issue will be fixed in near future.

@nschonni I haven't followed the translations on his repo so if this is sorted or if it will be sorted, feel free to close this issue.

Crowdin is hooked up now, but it's not really used. Primarily the changes comes as PRs to the repo
