Improved JSON Report with Diff Exclusion and Parameter Logging

[matteogreek]

Changes in this pull request:

1. Added a new feature to exclude the diff information from the JSON report. Users can now choose to remove the diff field from the JSON reports in two ways:
   • Using the CLI option --no-diff when running the CLI version of Prospector. Example of execution with the --no-diff option:

     ./run_prospector.sh CVE-2020-1925 --repository https://github.com/apache/olingo-odata4 --no-diff

   • Setting the no_diff parameter to True in the config.yaml file. By default the value is set to False.

     ...
     report:
      format: json
      name: prospector-report
      no_diff: False
     ...

This improvement aims to generate lighter JSON reports. Previously, for each commit, the entire diff was saved in the report, resulting in long and heavy files. By providing the option to exclude the diff, we make the reports more concise and easier to manage.

2. The JSON report now includes a new field called parameters. This field contains the exact values passed to the prospector function during execution. With this addition, users can now easily track and understand the specific parameters used to generate the results by opening the report file. An example of the JSON report with the parameters tracking is the following:

"parameters": {
       "vulnerability_id": "CVE-2020-1925",
       "repository_url": "https://github.com/apache/olingo-odata4",
       "publication_date": "",
       "vuln_descr": null,
       "version_interval": "None:None",
       "modified_files": [],
       "advisory_keywords": [],
       "use_nvd": true,
       "backend_address": "http://backend:8000",
       "use_backend": "always",
       "git_cache": "/tmp/gitcache",
       "limit_candidates": 2000
   },
