Add page tests should use latest UI labels like "Import from Git" instead of mapping "From Devfile" strings

There are different code spots which maps the old action items "From Git", "From Dockerfile" and "From Devfile" to the new action "Import from Git".

We should avoid mapping different strings to the new version and instead update our tests so that the feature and page object files matches the latest frontend code.

Code areas I found are marked with
