Change all public types in namespace Cysharp.Text to internal (#372)

* Change all public types in namespace Cysharp.Text to internal

* Regression caused by #368
* Stop namespace collision with Cysharp.Text nuget package
* Affects: class, struct, interface, delegate, enum
* using https://github.com/zzzprojects/findandreplace on command line, so we can automate this step:
"fnr.exe" --cl --dir "SmartFormat.ZString\repo\src\ZString" --fileMask "*.cs,*.tt" --includeSubDirectories --caseSensitive --useRegEx --find "public (?=.*(class |struct |enum |interface |delegate ))" --replace "internal "

* Add a unit test to get an alert when Cysharp.Text objects are public

* Bump version to v3.3.2
