This pull request includes changes to improve code readability and consistency across several files. The most important changes include modifying the pow function in the Arduino generator, reformatting imports, updating typography usage, and removing an experimental badge from the navbar.

Improvements to code readability and consistency:

• src/components/Blockly/generator/math.js: Changed the pow function call from Math.pow to pow for consistency with C++ syntax.
• src/components/CodeEditor/LibrariesAccordion.jsx: Reformatted the import statements for better readability.
• src/components/CodeEditor/LibrariesAccordion.jsx: Simplified the Typography component usage by removing the variant attribute where it was not necessary. [1] [2]
• src/components/Navbar.jsx: Removed the "Experimental" badge from the "Code Editor" menu item for a cleaner UI.
