datasource item nullable project

[peter-malcolm-bw]

Describe the bug
A clear and concise description of what the bug is.

• I am unable to list all of the datasources on the server.

• This looks like the same issue as Workbook item nullable project #1028 except with DatasourceItem instead of WorkbookItem

Versions
Details of your environment, including:

• Tableau Server version (or note if using Tableau Online) - Tableau Online
• Python version: 3.9.12
• TSC library version: 0.24

To Reproduce
Steps to reproduce the behaviour. Please include a code snippet where possible.

import tableauserverclient as TSC

# log in to tableau server 

for datasource in TSC.Pager(server.datasources):
      print(datasource)

The error can be fixed by removing one line from datasource_item.py:

class DatasourceItem(object):
    
    ...
    
    @project_id.setter
    #@property_not_nullable  # TODO: remove this line 
    def project_id(self, value: str):
        self._project_id = value

Results
What are the results or error messages received?

yep - this should be simple enough to get in a new release very soon.
