8374342: Remove incorrect @throws NoSuchFileException from FileUtils.java

[thswlsqls]

Summary

Remove incorrect @throws documentation from FileUtils.deleteFileIfExistsWithRetry.

Description

The method documentation states that no exception is thrown if the file does not exist.
The implementation checks file existence before deletion and does not throw NoSuchFileException in this case.
This change removes the contradictory @throws clause.
No behavior is changed.
