Summary

Remove the preview status for the methods String::stripIndent, String::translateEscapes and String::formatted. These methods are required support for the Text Blocks language feature which is being moved from preview status to standard language feature status.

Problem

The preview status of these methods prevents usage in standard Java.

Solution

Remove the preview status requirement from these methods.
