Redundant embedded expression in string template

Reports redundant embedded expressions in STR templates, such as trivial literals or empty expressions.

Example:

System.out.println(STR."Hello \{"world"}");

After the quick-fix is applied:

System.out.println(STR."Hello world");

This inspection depends on the Java feature 'String templates' which is available since Java 21-preview.

New in 2023.3
