[test-only] setup playwright test - #102

• deleted cucumber from test setup.
• instaled playwright as the only framework for ui testing, what gives us:
  • using vscode extension we can run the test by pressing the button
  • It is easy to select a browser for the test. or run the test in all browsers at once
  • It is easy to disable/enable headless mode or run test and see result in trace viewer
  • debuging testing has become much more convenient
• created example test createDrawio file
• here test structure. I wan to keep in the web-apps. and use pagesObjects and helpers in a separate folder (see structure here Readmi )
• tests uses POM like here https://playwright.dev/docs/pom

here I tried to demonstrate how to run test using platwright extension
