This commit adds a service worker to make the app installable as a PWA.
In addition to caching all generated build artifacts (css and js filse)
the service worker also caches all other static files via a
stale-while-revalidate strategy (png, ico, json, css from the public
folder).
Further, this commit adds a Notification which will be shown when the
service worker updates and clicking on the button inside it causes
the service worker to update and the page to reload.
In order to make a PWA installable we need to follow some guide lines:

create-react-app seems to struggle a bit [1] and many folks are
recommending vite as an alternative, as that project is more active.
For me the reason to switch to vite is to reduce dependencies and speed
up the build process.
Replacing create-react-app with vite reduce the number of dependencies
from 1762 to 444.
I was also quite surprised, by how small the actual diff in this commit
is. From that perspective there is almost no discernible difference
between the two tools.
