SDK sets default locale for JVM

[gombosg]

Version

What package version of the SDK are you using.
4.14.2

Describe the bug

Very strange localization issues appeared in our production application, like formatting dates in Chinese, Portuguese etc. Incidentally, soon after rolling out our Teams app which is part of our backend monolith. Turns out the SDK sets the default locale since #1074 with Locale.setDefault() which is JVM global.

To Reproduce

Steps to reproduce the behavior:

1. Send a message to a bot with locale other than en_US
2. Default locale changes, verify with Locale.getDefault()

Expected behavior

Locale.setDefault() is not run by the SDK as it's JVM-wide.

Hi @gombosg,

Thank you for the report.

Unfortunately, at this time there are no updates scheduled for the Java SDK, barring any major security fixes that need to be addressed.
