Issue #, if available:

Description of changes:

• Add test_version.py to ensure that we don't accidentally do a release with a version that doesn't include an explicit micro / minor version. For example, we released 1.2 instead of 1.2.0. While 1.2 is technically valid, it causes issues with some AWS logic such as docker builds that expect an explicit micro version.
• Update the way we create our version.py file so the content aligns with the ruff formater. Previously it complained that the version file lacked a newline and should use " instead of ' for string values. This would lead to unnecessary clutter and confusing when users would perform automated linting prior to submitting a PR.

Example of the previous confusing lint message:

ruff format --diff "timeseries/"
--- timeseries/src/autogluon/timeseries/version.py
+++ timeseries/src/autogluon/timeseries/version.py
@@ -1,2 +1,3 @@
 """This is the autogluon version file."""
-__version__ = '1.2'
+
+__version__ = "1.2"

1 file would be reformatted, 65 files already formatted
