ESLint v8.40.0 released

Highlights

• Rules can now use properties context.sourceCode, context.cwd, context.filename, and context.physicalFilename instead of methods context.getSourceCode(), context.getCwd(), context.getFilename(), and context.getPhysicalFilename() respectively. The methods are now considered deprecated.
• The FlatESLint class has a new method findConfigFile(). It returns the path to the config file being used by the instance or undefined if no config file is being used.
• The semi rule has a new option omitLastInOneLineClassBody.
