* Fix the type declaration of `!!raw-loader!` modules.
Instead of declaring them to export an object with a single key
`default` which is a string, the modules have a default export, which
is a string.
Note, that this doesn't actually change the generated code, just the
types that typescript sees. The code worked before because the only
thing done to the values was to coerce the values to a string, which
turned into a no-op.
* Switch from using `raw-loader` to using a source asset module.
`raw-loader` was deprecated in webpack v5.
Cypress and Jest both define "expect", but they come from different
libraries (Cypress uses Chai, Jest uses its own thing). So we can't
include both of them in the tsconfig.json. Conveniently, however, we
don't need any of the test code to be part of the main project, so
it suffices to give these things their own tsconfig.json files.
That being done, adding "jest" to the global types lets us remove all
those imports.
