Change JSON serialization unit tests to deterministic implementation

[anthonyx24]

Issue

Hello, this is a direct follow-up to my previous PR: #1546 . These tests all may be nondeterministic due to the same reason, which is JSON parameter ordering not guaranteed by Jackson's default ObjectMapper.

Again, these tests were detected via the Nondex tool, which flags Java tests that are potentially nondeterministic due to underlying assumptions regarding the Java API. In total, 11 tests were flagged (10 fixed here, 1 fixed in the previous PR):

org.telegram.telegrambots.meta.test.TestSerialization.testSendLocation

Potential Fix

As detailed in the other PR's description, the fix I implemented is to explicitly configure the ObjectMapper to sort the JSON parameters alphabetically during serialization. Then, I manually sort the parameters of the expected JSON strings. The tests still pass (verified with mvn clean test), and Nondex also shows a passing result now.

I know this seems like quite a large PR, but I'm just applying the same approach 10 times. Please let me know regarding feedback or questions. Thank you!
