[FEAT][MAINT][4019] Make multi-modal easier to configure in seedprompt files

[shivenchawla]

Description

Issue: #695

Right now, images are configured like this in yaml (e.g., illegal-multimodal.prompt)

• dataset_name: TestMultimodalTextImageAudioVideo
  harm_categories:
  • illegal
    source: AI Red Team
    value: ......\assets\pyrit_architecture.png
    data_type: image_path
    sequence: 1
• dataset_name: TestMultimodalTextImageAudioVideo
  harm_categories:
  • illegal

These relative paths break when using in different contexts. For example, you can't use them in both jupyter notebooks and unit tests.
As part of this issue, we try to make it easier to use yaml across contexts.

Proposed solution:

1. Path as:
   {pyrit_root}/assets/image.png or $pyrit_root/assets/image.png

2. Using the other configured paths - e.g. see path.py

Tests and Documentation

Notebook sample and JupyText available at this path:

1. Notebook: PyRIT\doc\code\memory\8_seed_prompt_database.ipynb
2. JupyText: #PyRIT\doc\code\memory\8_seed_prompt_database.py
