Remove duplicated index.html file

This commit removes the redundant `index.html` file from the
`src/presentation/public` directory. This file was initially created
there with Vue CLI before migration to Vite. The existence of this file
is now unnecessary as Vite requires `index.html` to be at the project
root.

The deletion of this duplicate file simplifies the project and
eliminates potential confusion regarding the entry point of the
application.

Changes:

- Update `docs/presentation.md` to clarify the location of `index.html`.
- Remove the `src/presentation/public/index.html` file, which was
  duplicate of the project root `index.html`.

These changes ensure compliance with Vite's configuration and project
structure clarity.
