participate link to Reddit does not point to Reddit

[BrauerSuzuki]

On https://www.thunderbird.net/de/participate/ there is a link called 'Reddit', which points to https://www.thunderbird.net/de.

Wrong for all languages https://www.thunderbird.net/en-US/participate/ > "Promote" > reddit is not pointing to https://www.reddit.com/r/Thunderbird/ @MelissaAutumn.

Yeah the participate & social links were reorganized in #759 and I think the correct setting is just missing — I'll check whether 4c1cfa4 is all that's needed and will submit a fix shortly.
