Vouch request to add a new translation

[kostich]

What do you want to change?

I would like to add a new translation for the sr request. Already opened a PR that was swiftly killed. :)

Why do you want to make this change?

I would like to use Ghostty on Fedora in my native language.

I acknowledge that:

• I have read the Contributing Guide and understand the contribution process.
• I have read and agree to follow the AI Usage Policy.
• I wrote this vouch request myself, in my own voice, without AI generating it.
