[lancegliser]

• I have searched the Issues to see if this bug has already been reported
• I have tested the latest version

Steps to reproduce

1. Go to https://www.flowbite-react.com/docs/components/table
2. Turn on dark mode
3. Open dev tools
4. Inspect table header cells

Current behavior

The current table component headers cells use dark:text-gray-400 on top of dark:bg-gray-700.

Expected behavior

Accessibility standards for table headers pass AA standards.

Context

If the text us updated to use dark:text-gray-300 the result is 6.99 ratio passing accessibility standards.

If possible, provide a live example URL, screenshot, video, or a repository with the minimal reproduction of the issue.
