Add Red/Green/Blue (Japan) version resources and related data

[jemarq04]

A follow-up PR to issue #1234. The Japanese releases of Red/Green/Blue were not listed in versions/version groups, so I added these and changed the order column within version_groups.csv accordingly. Also, in adding the name of these games in various languages, I noticed that Pokemon Blue (international) was listed as "緑" in Japanese, which actually means green in English, so I fixed this as well.

For the names of the versions in different languages, I used the following Bulbapedia pages:

• https://bulbapedia.bulbagarden.net/wiki/Pok%C3%A9mon_Red_and_Green_Versions#In_other_languages
• https://bulbapedia.bulbagarden.net/wiki/Pok%C3%A9mon_Blue_Version_(Japanese)#In_other_languages
• https://bulbapedia.bulbagarden.net/wiki/Pok%C3%A9mon_Red_and_Blue_Versions#In_other_languages

I added the following data for these new versions:

• Three version resources: red-japan, green-japan, and blue-japan.
• Two version group resources: red-green-japan and blue-japan.
• References to the new version groups in the kanto pokedex resource.
• Move learn methods available in the new version groups (mirroring Red/Blue (international)).
• References to kanto region resource for the new version groups.

Other data related to the new versions has not been added yet (locations, encounter data, pokemon sprites, etc.). A lot of it may be able to be copied from the international releases from a detailed website here: https://altissimo1.github.io/Main-Series/RGBY/rgby-differences.html. This is not a known "reputable" source, so I'm not sure if we should use this, but it is something that I found. I'm interested in others' thoughts.

Great of you having found that resource!

Great of you having found that resource!

I'll work on implementing the details using PokeAPI and that website - I'll put in a PR once I've updated and tested everything

As always, if you have time and will go on and feel free to work on this issue, that resource is good enough for our use

A PokeAPI/api-data refresh has started. In ~45 minutes the staging branch of PokeAPI/api-data will be pushed with the new generated data.

The staging branch will be deployed in our staging environment and the entire API will be ready to review.

A Pull Request (master<-staging) will be also created at PokeAPI/api-data and assigned to the PokeAPI Core team to be reviewed. If approved and merged new data will soon be available worldwide at pokeapi.co.

The updater script has finished its job and has now opened a Pull Request towards PokeAPI/api-data with the updated data.

The Pull Request can be seen deployed in our staging environment when CircleCI deploy will be finished (check the start time of the last build).
