Update folder name to underscore

[SirPhoeniix]

I have noticed that the documentation says that the folder for your translations should be de-DE or en-GB. I have updated this in this pull request because I had to name the folders de_DE and en_GB to get translations working.

@shyim This was changed in this PR. Did something really change in core?

@SirPhoeniix can you please provide the version you have tested / used this on ?

[shyim]

@tobiasberge do you maybe know?

@shyim Looks correct to me, in the core underscore is also used.

@SirPhoeniix can you please provide the version you have tested / used this on ?

I am using version 6.6.5.1, but it looks like the PR was already merged :)

The tutorial page still claims the folder structure should be
└── SwagBasicExample
└── src
├─ Resources
│ └─ snippet
│ ├─ de_DE
│ │ └─ example.de-DE.json
│ └─ en_GB
│ └─ example.en-GB.json
└─ SwagBasicExample.php
At least in 6.6.7.1 the folder has to be named with a '-'. Also that would be an opportunity to clarify which locale notation is used. Underscore seems to follow the ICU definition while the dash notation seems to be used by ISO.

hey @Ideosynkrat
it seems that the directory structure does not matter at all 😬

I will investigate further on this and will update the article accordingly then
