Workflow fails if categories property is missing in the properties file

[SableRaf]

Description:

The workflow currently fails if the categories property is missing from the properties file provided as input. This results in a KeyError when attempting to access props['categories'].

Error log excerpt:

File "/home/runner/work/processing-contributions/processing-contributions/scripts/add_new_contribution_to_yaml.py", line 18, in <module>
    if props['categories']:
       ~~~~~^^^^^^^^^^^^^^
KeyError: 'categories'
Error: Process completed with exit code 1.

Steps to Reproduce:

1. Run the workflow with a properties file that does not include the categories property (for example: https://github.com/KrabCode/LazyGui/releases/download/latest/LazyGui.txt)
2. Observe the workflow failing with the above error.

Proposed Solution:

Add a check for the existence of the key and provide a default value (None) if it is not present:

if 'categories' in props and props['categories']:
    props['categories'] = sorted(props['categories'].replace('"', '').split(','))
    props['categories'] = [category.strip() for category in props['categories']]
else:
    props['categories'] = None

Additional Notes

I'll make a PR shortly that will address this issue.

There was an error in reading your properties file or parsing it.

Please ensure that the URL is correct and the file follows the required format.
