chore(PPDSC-1581): upgrade to cypress 12

[mstuartf]

PPDSC-1581

What

1. Background - why this is needed
2. What did you do

• Renamed all files as required / updated extensions
• Moved config files to root dir
• Added handler to stop uncaught exceptions failing tests
• Updated setup for test_newskit_in_nextjs_app job

3. What does the reviewers should expect

• Existing cypress tests pass

I have done:

• Written unit tests against changes
• Written functional tests against the component and/or NewsKit site
• Updated relevant documentation

I have tested manually:

• The feature's functionality is working as expected on Chrome, Firefox, Safari and Edge
• The screen reader reads and flows through the elements as expected.
• There are no new errors in the browser console coming from this PR.
• When visual test is not added, it renders correctly on different browsers and mobile viewports (Safari, Firefox, small mobile viewport, tablet)
• The Playground feature is working as expected

In search.cy.js, please remove "cy.contains('Search').click({force: true});" and bring back "cy.get(${DESKTOP_NAV} ${SEARCH_BTN}).click();"

This was just a temporary hack I needed to do to keep the tests running after the recent upgrade of next.js to v.13

Nice one! Do you think it's worth using the component testing feature or it's not needed for now?

[Xin00163]

Do we need this plugin for docs?

[mstuartf]

We do but you make a good point as we don't need it for any of the others. Will remove!

[Xin00163]

would it be OK just to import the file const setupNodeEvents = require('./cypress/plugins/index.js')? https://docs.cypress.io/guides/references/migration-guide#Config-Option-Changes

[mstuartf]

Updated to match the intended new structure. Will just check the pipeline is ok then ready for another look. Thanks!
