internationalize the docs upload and canonical url

[tfoote]

This must be merged in conjunction with the server crossover

[dirk-thomas]

Since EOL distros aren't being regenerated why update those entries? I assume the old URLs will be redirected to the new layout anyway (and maybe existing canonical URLs replaced with the new)?

[tfoote]

I updated them all because if they're not deleted they are presumably being kept to be potentially turned on again by us in the future or by someone else. This will make it consistent and able to be turned back on. If we don't want to maintain them we should probably just remove them entirely.

There will be redirects for all the legacy urls.

Looks good. Shouldn't be merged until the server operation has been performed.
