STCLI-255 add stripes test cypress command

[JohnC-80]

This PR adds the cypress sub-command to the test command..

Run cypress tests headlessly...

stripes test cypress

Run cypress tests in the cypress UI (handy for development)

stripes test cypress --cypress.open

Since cypress insists that repos contain their own cypress.config.js file, stripes-cli exports a function to generate a base configuration - it generates the defaults internally and can be used at the repo level to override the configuration. stripes-components PR for example use: https://github.com/folio-org/stripes-components/pull/2386/files#diff-5bae461d15457335f3d6285d35d3df2fd618e583eb7460c52cd8f0de69627abc

We'll have to determine if other 'cypress resources' are necessary and automatically added when cypress is implemented via this tooling - will have to try it with nothing...

This code adds a first draft for a standalone function that generates a webpack configuration without requiring a previous setup of a platform or "StripesCore" (ahem stripes-webpack.)

Remaining work:

Documentation!
Add code coverage support!
Attempt to convert stripes-core and stripes-smart-components
