fix: add favicon.ico support

[GulshanJha00]

Fixes #134

Added favicon.ico support by:

• adding a root favicon.ico file
• configuring Eleventy passthrough copy
• linking the favicon in the document head

This resolves the 404 issue for /favicon.ico.

Code Review

This pull request adds favicon support by configuring the Eleventy passthrough and adding the icon link to the main template. It also includes a layout adjustment for the developer list. Feedback suggests removing the hardcoded versioning from the favicon link and using standard Tailwind spacing classes instead of arbitrary values for the layout change, which should ideally be handled in a separate commit.

This layout change (min-w-[150px]) appears to be unrelated to the favicon support described in the PR title and description. To maintain code quality and follow the principle of atomic commits, unrelated changes should be handled in a separate pull request. Additionally, consider using standard Tailwind spacing classes (e.g., min-w-36 or min-w-40) instead of arbitrary values to ensure consistency with the design system.
