Add theme toggle in HTML report

Fixes Issue

• [HTML-REPORT][BUG]Interactive report missing the Light and Dark mode switch #694

PR Branch
https://github.com/bppdanto-t/zerocode/tree/add-theme-toggle

Motivation and Context

Due to version update of extentreport library, the toggle theme icon is missing from the HTML report. While toggling the theme is still achievable by pressing "L" key with keyboard, there's not much visibility to the user on how to do it. This PR will add the toggle icon back and move it to the top right side, as requested by @authorjapps (comment link).

Light theme

Dark theme
