Document language support for taginfo

[1ec5]

Factored out the language list as a plain text file for easier diffing. Now running the rendering script also uses this file to generate a taginfo project file listing all the supported name:* subkeys. In the future, the project file template can be extended to cover other tags defined in layers (#2). The code that generates the project file requires jq for convenience, but if it’s a hassle to install that tool, we can replace it with some additional sed hackery or somesuch.

This will need a rethink as of #24. I guess we could do something like pull the full list of name:*=* subkeys from taginfo just to populate a taginfo project file that says the same thing for each one. 😂

OpenHistoricalMap’s Tegola-based tile server has a step that monitors the database for these subkeys, which could help populate the project file: OpenHistoricalMap/issues#604 (comment). I don’t know if Planetiler has a similar hook, but if not, we could call out to the taginfo API to get these statistics.
