Docs/bpmn diagram viewer component issue 56

[sgort]

Closes #56

Render interactive BPMN diagrams in the Docusaurus documentation while keeping BPMN files alongside their markdown content in docs/.

[sgort]

Reference issue

There is an issue with original references in the markdown files.

For example in file docs\documentation\reference\bpmn20\events\error-events.md the reference is <div data-bpmn-diagram="../bpmn/catchandthrowpattern"></div>, where the file is in docs\documentation\reference\bpmn20\events\bpmn\catchandthrowpattern.bpmn

That is wrong.

Fix

With fix-bpmn-references.js all of these references are changed from ../ into ./.

The diagrams are rendering now. Still need to check all individual files. But PR is ready for review.

[sgort]

I checked all the files.

Only [fix-bpmn] 1 reference(s) fixed in: C:\Users\mail\Development\documentation\docs\documentation\user-guide\process-engine\transactions-in-processes.md is not working.

There is no event-based-gateway.bpmn file in docs\documentation\user-guide\process-engine\bpmn. So this rendering error is correct.
