feat: implementation of cypress e2e with some minor test cases.

To test, pull the branch in local.

• Add entry point https://ahikar-dev.sub.uni-goettingen.de/api/textapi/ahikar/arabic-karshuni/collection.json and run the application. The app loads in the port 8080.
• Added new test id's inside the components to perform test cases. Since these are not available to dev or live, using the localhost as a base url in cypress.json config.
• Open a new console tab to run tests - npm run cypress, as soon the cypress console is opened we can view the app.test.js file and select it. This runs the tests on Chrome browser.

Note:

• gitlab pipeline were because of the new test config. Will check the scripts and update the MR.
