@TolichP [1] reported in #3 [2
`install.sh` script replaced the `config` file which led to
configuration/data loss. This was caused by the `-f` flag passed to the
`cp` command [3] which forced to override existing files.

This is a really critical bug and the the solution to provide a script
that automatically handles the simple task of copying a file has never
been a good idea at all. Therefore the script was removed and the
documentation has been adjusted to provide manual installation steps
instead like in other port projects, e.g. Nord Alacritty [4].
The manual steps are quite simple and the knowledge can be expected of
users since these are basic operations when running a Unix system.

Projects like Terminato, that require to modify the main user
configuration file instead of providing a way to load features like
themes from dedicated file, are always way harder to support as a
theme author. Anyway, there are plans to unify the installation of Nord
port projects through one universal automation tool,
but there is currently no ETA.

Fixes GH-12

Removed missing GitHub favicon, made the badges the same color and changed to the new footer image.
Also capitalized "release" to match all other badges.

The configuration code in the README contained an invalid blank space within the `palette` key value that causes Terminator to crash when using a profile with this configuration.

With the retirement of the "Arctic Ice Studio" personal & Nord project
brand [1] various migrations to the `svengreb` GitHub account [2] of
other projects were also completed within the last weeks. There are also
changes in Nord projects like `nordtheme/web` that other projects
depended on and can now be adapted as well.
Therefore all Nord projects must adapt these changes which includes...

- the migration and repository name change of
  `arcticicestudio/nord-docs`[2] - all references must be updated.
- the migration of the `arcticicestudio/styleguide-git` repository to
  the `svengreb` "real-in-person" identity [3] - all references and
  used npm packages must be updated.
- the migration of the `arcticicestudio/styleguide-javascript`
  repository to the `svengreb` "real-in-person" identity [4] - all
  references and used npm packages must be updated.
- the migration of the `arcticicestudio/styleguide-markdown` repository
  to the `svengreb` "real-in-person" identity [5] - all references and
  used npm packages must be updated.
