Try clean unused imports

[tutosrive]

This pull request introduces several improvements and cleanups across the codebase, focusing on UI enhancements, code maintenance, and removal of unused or commented-out code. The most significant update is the addition of a new "Supported Languages" section on the Home page, which visually showcases the experimental languages in a carousel. Other changes involve removing unused code and dependencies, and minor code cleanups.

UI Improvements:

• Added a new "Supported Languages (Experimental)" section to the Home page, featuring a carousel that displays images for Python, Ruby, Lua, JavaScript, and PHP. This section helps users quickly see which languages are supported. [1] [2]

Code Cleanup and Maintenance:

• Removed unused or commented-out code, such as the commented import of StrictMode in src/main.tsx, the Selector component in CodapiCustom.tsx, and an old stylesheet/script reference in index.html. [1] [2] [3]
• Commented out unused code and the exec function in src/ts/codapi.ts, and removed the axios dependency since it is no longer used in the file. [1] [2]

Minor Adjustments:

• Added a no-op usage of ace.toString(); in Playground.tsx, likely to ensure the ace import is not tree-shaken.
• Cleaned up unused state and effects in the Playground page, including removing the scripts state and related effect.
• Simplified an event listener callback in Playground.tsx by removing the unused event parameter.
• Removed outdated comments in the themesOptionsFromList utility.
