This PR replaces placeholder and outdated Jira Data Center integration documentation with a detailed, step-by-step setup guide for configuring OAuth 2.0 credentials in Jira Data Center and integrating with Nango. It refines the access requirements table, converts 'Useful links' into a more readable list, adds clear scope documentation, and streamlines the API gotchas, directly addressing prior review feedback for clarity and conciseness.

Key Changes:
• Complete rewrite of docs-v2/integrations/all/jira-data-center.mdx to add a multi-step, actionable setup guide using Steps/Step components.
• Clarified and reformatted the 'Access requirements' section with specific comments and conditional requirements.
• Converted the 'Useful links' section from a table to a markdown list and updated external references.
• Added a dedicated 'Common Scopes' section referencing official Atlassian documentation.
• Simplified the 'API gotchas' section by removing outdated or unnecessary implementation details.

Affected Areas:
• docs-v2/integrations/all/jira-data-center.mdx
