Great news. Congratulations on your hard work. 🌸

The above text is not incorrect, but I would suggest using the following to make it more fluent.

Türkçe yazdığınızı ancak bunun için uygun dil etiketini kullanmadığınızı fark ettik. Gelecekte erişim alanınızı artırmak için bu etiketi kullanmanızı öneririz.

Both forms are correct.

There is also a possibility to link a discord community server in future reports if you know about a welcoming one

I think you meant the Discord server that we can recommend to new members who join and write in Turkish, right? Currently, there is the Trliste Discord server that supports members who write in Turkish. https://discord.gg/PkNnhb73pe
