Remove legacy wiki-side generation after moving to Github

[brliron]

We moved base_tsa from MediaWiki to Github 9 years ago, yet we still have way too much stuff that this move made obsolete. Things like https://browse.thpatch.net/lang_ja/th185.js , https://browse.thpatch.net/lang_ja/th14.v1.00b.js , or the entirety of https://browse.thpatch.net/base_tsa/ don't have any reason to exist anymore. Most of them are also terribly outdated, which means they're quite likely to break things if they're used.

We should work on removing them. For each file (or section of a file), it can be done in 3 steps:

• Replace the MediaWiki page (or part of the MediaWiki page) generating them with the "moved to Github" template.
• Remove the file on the server, and set it to null in files.js.
• Remove the generation code in this repo if it isn't needed anymore.

Sometimes, you won't have to do all 3 steps. For example, lang_ja/th185.js doesn't have the "replace the MediaWiki page" step because we still want our nice-looking header on the wiki, we just want it to not generate any patch file. Or lang_ja/th14.v1.00b.js doesn't have the "remove the generation code" step because that code is also used by the skipgame patch, which is still hosted on MediaWiki (we could move it to Github, but that's another question).

Rather than removing the pages outright, just empty them and keep the "moved to github" template. This keeps the revision history publicly available.

We have such a template? I didn't know.
