Incorrect language code for Tamil in i18n files

[hegotit]

Description

The language code for Tamil is currently listed as taTA, which isn't a valid country/region code. The correct language codes for Tamil in different regions should be:

taIN for Tamil in India
taLK for Tamil in Sri Lanka
taSG for Tamil in Singapore
taMY for Tamil in Malaysia

TA is not a recognized country/region code. Using one of these will help with proper localization and compatibility.

By the way, in the Chinese version of the release notes of v1.5.8, the text 泰国 (Thailand) seems to be incorrect and might need to be replaced with an appropriate one.

Thanks for your feedback, I will update the release notes and correct taTa to taIn.
