python3Packages.syrupy: fix wrong version disabler

`pythonOlder` only checks for major and minor version specifiers of python.

However, https://github.com/tophat/syrupy/releases/tag/v4.0.0 specifies that 3.8.1 is the minimum supported release.

Currently, although deprecated, the provided python38 version is 3.8.17. Thus this package should be available.
