Integrate into Haystack Home

[TuanaCelik]

We need to integrate the .md files in the /integrations directory here into Haystack Home. The idea is that it would work similar to the tutorials repo -> When an .md is merged onto this repo, it's pushed to haystack-home too.
The .md files (for now) have the following frontmatter:

---
name: Azure Translate Node
description: TranslateAnswer and TranslateQuery Nodes that use the Azure Translate endpoint
authors:
    - name: recrudesce (Russ)
      socials:
        github: recrudesce
        twitter: recrudesce
pypi:
repo: https://github.com/recrudesce/haystack_translate_node
type: Custom Node
report_issue: https://github.com/recrudesce/haystack_translate_node/issues
---

To be discplayed on the cards on https://haystack.deepsret.ai/integrations:

• name
• description
• 'Type' as a tag (like we have the level tags on Tutorials)

To be used as filters:

• type

When opened, display page or modal (like the prompthub modal):

• Render the authors and their socials
• Render some sort of buttons below the Title (name), description and authors the options such as "PyPI package" and "GitHub repo"
• Render a 'report and issue' button separatelly (to the right?) that forwards to the url mentioned in the frontmatter.
• Render the content in similar style to the tutorial content

We can copy this layout:

The only change I woule like to have is to have the card colors inverted to what we have here (dark purple background with white text)

Next steps will be:

• We want to have 'upvote and downvote' functionality
• We would like to have search capability.
