Linting and re-indentation for all scripts

All scripts have been cleaned up, using ESLint (non-necessary variables, mistakes, etc.) and have been re-indented properly using JS Beautifier.

Some minor fixes have also been made on all repositeries on Github:

• Repositery of Van11y accessible tabpanel
• Repositery of Van11y accessible accordion
• Repositery of Van11y accessible hide/show
• Repositery of Van11y accessible tooltip
