…thon virtual environment

Updated the Flask route '/get_default_values_for_backend' to dynamically provide default values for project creation/editing based on the selected backend.
Added logic in the Python backend to determine and return default values such as name, homepage, version URL, version scheme, version pattern, version prefix, pre-release filter, and version filter.
Integrated JavaScript code to handle AJAX requests and populate form fields with default values retrieved from the server based on the selected backend.
Improved user experience by enabling users to effortlessly fill in project details with default values, enhancing efficiency and ease of use.

Now is such that, the homepage is entered by user as a url
and then that is sent to the backend to get the project with that url
then fields are autofilled with the data received
