Wrong Timezone value for Asia/Almaty in Inputs Settings

[slayerjk]

Hi,

From 1 of March 2024 Timezone all over Kazakhstan is GMT+5 including(Asia/Almaty tz).

But Graylog(version is 5.2.6) still knows about Asia/Almaty is GMT+6.

I've noticed this while searching for logs in web console where timestamps were incorrect.
I've found the troublemaker in Inputs setting - Timezone option was incorrect.

I know it's no such problem to switch, for example to Asia/Aqtau or GMT+5, but I'd like to know if this will be fixed?

According to an email on the tz mailing list, Kostanay Region could be part of Asia/Qyzylorda

We might want to check if the issue is still present in 6.0.

I've upgraded to 6.0 and TZ is fixed here.
