[enhancement] Dark mode for contributor's page

[RajMhatre20]

Working on the contributor's page at night was tougher than comprehending Urfi Javed's dressing sense! That blinding white background nearly turned me into a nocturnal snowman. I'm pretty sure that anyone switching from dark mode to that page would get their retinas sunburned!

Suggestion: Add dark mode on all contributor's pages and to maintain consistent design across all pages, we can do the following:

1. Replace the GitHub icon with a dark mode button.
2. Move the GitHub icon to the AlgoListed Updates icon's position.
3. Shift the AlgoListed Updates icon to the left side, following the 'Buy Me a Coffee' button.

Thank you for bringing it to my attention; I'll address it on my own shortly.
