Message:

Code Editor: Switch from Esprima to Espree for JavaScript linting in CodeMirror.

Esprima is no longer maintained, and it does not support the latest JavaScript features in ES11, as Espree does.

• New Linter Integration: Introduces src/js/_enqueues/vendor/codemirror/javascript-lint.js using espree for parsing and error reporting, replacing the dependency on jshint and esprima scripts.
• Script Modules: Registers espree as a script module and leverages the module_dependencies argument in wp_register_script() to ensure espree is available as a dynamic import.
• Editor Settings: Updates wp_get_code_editor_settings() to use ES11 (ECMAScript 2020) defaults and synchronizes JSHint settings from .jshintrc for compatibility.
• Editable Extensions: Adds .mjs to the list of editable file extensions for plugins and themes.
• Deprecations: Marks esprima and jshint script handles as deprecated.
• Build Tools: Updates Webpack configuration to bundle espree as a module and use the new local javascript-lint.js.
