Return set output

[NenadJovicic]

Added back to have output of action, because exporting env variable won't work in cases like customer-apps where in one job, we have to calculate multiple deployment names, so env variable will be overriden

Not removing exportVariable because not sure does anyone use v2 of action, can't be found through github search. Looks like github search does not include .github folder in search

Here you can find used versions https://github.com/search?q=org%3Alocal-ch+calculate-deployment-name%40&type=code some apps use v2

@crappylime I didn't break anything in functionality
I tried same search, but for some reason, it didn't give me any results 😅
thanks
all are under our control, some of them are archived, or should be archived, and I didn't make any breaking changes
so we should be fine

It would be nice to mention in Readme which version is for what since I saw three different versions used in apps I guess for different reasons

[NenadJovicic]

well, only projects on which Coa worked on have v2 used, because he updated it, and haven't thought about other use cases, and haven't updated any other project
v1 should be deprecated, because it uses old node version which won't be allowed soon by github actions
and in general, we should use latest v2
I will just update example in readme to show both options, env variable and output
