Getting Tamil onto nodejs.org

nodejs.org runs its translations through Crowdin, but a locale has to be configured in the codebase before any translator can touch it. Tamil wasn't in there yet. So before any actual translating happened, I opened an issue requesting it, then added the language entry to config.json and wired it into the site's i18n setup so Crowdin would pick it up.

After that landed, most of what I sent in was small fixes I ran into while working through the docs: a broken markdown link on the Previous Releases page that was just sitting there as plain text, a CodeTabs component that was naming its tabs inconsistently, a couple of other formatting cleanups. None of it required much thought. It's just what turns up when you're reading a large docs site closely enough to translate it.

The locale is live now at nodejs.org/ta. The real pull request and issue history is on the Open Source page, if you want to see exactly what changed.
