Update the wiki

[briatte]

Some of the linked resources are probably outdated or unavailable.

Course utilities is the most useful, at least to me. I keep rediscovering some of the stuff it lists…

Data lists stuff that I communicate to students.

The course history was never clear or accurate… Let's see if planning for 2.0 (#31) helps.

The "Code" wiki page does not exactly correspond to what I teach students. For instance, my first session focuses almost just on pwd…

The "Stata" wiki page links only to English-language stuff, but I could add @methevenin's courses in French, which are very up-to-date:

https://mthevenin.github.io/stata_fr/
https://github.com/mthevenin/stata_fr
https://github.com/mthevenin/formation_stata

There are other pages, some with close to zero usefulness, unless I put the links or references in the Stata Guide, for instance. I keep re-creating lists of courses every time I teach a new course anyway.

Bottom line — use the wiki only to document the srqm internals (utilities), move everything else to the Stata Guide.
