fix: update OpenInference SDK link for Arize Phoenix integration

[PixelPil0t1]

I updated the outdated OpenInference SDK link from https://github.com/openinference/openinference to https://github.com/Arize-ai/openinference to reflect the current repository location.
If you have a better or more accurate source for the OpenInference SDK, please feel free to suggest it, and I will update it accordingly.

Code Review for PR #2703 in crewAIInc/crewAI

Summary of Key Findings

• Change Overview:
  The pull request modifies a single line in the documentation file docs/how-to/arize-phoenix-observability.mdx to update the GitHub URL of the OpenInference SDK from https://github.com/openinference/openinference to https://github.com/Arize-ai/openinference.

• Purpose:
  This update reflects the current and accurate location of the OpenInference repository, likely due to a project ownership or organizational move.

• Impact:
  Only documentation is updated; no source code or functional logic is touched. This improves user guidance by pointing to the correct external resource, preventing confusion or broken links.

Specific Code Improvements and Suggestions

1. Correctness and Appropriateness:
   The updated URL is correct and the change is necessary to maintain documentation relevance.

2. Documentation Quality:

   • Markdown syntax and formatting remain correct and clear.
   • There is no degradation of clarity; the sentence fully conveys integration instructions.

3. Optional Enhancements:

   • To improve conciseness and remove slight redundancy, revise the phrase
     "By the end of this guide, you will be able to trace your CrewAI agents and easily debug your agents."
     to
     "By the end of this guide, you will be able to trace and easily debug your CrewAI agents."

   • Consider updating the anchor text to clarify project ownership, e.g.,
     [OpenInference](https://github.com/Arize-ai/openinference) → [OpenInference by Arize](https://github.com/Arize-ai/openinference).

   • Audit the whole documentation set for references to the old URL to ensure consistency.

   • Where possible, link to official OpenInference documentation websites instead of directly to GitHub repositories to future-proof against further repo moves.

Historical Context and Related PRs

• Previous updates to this doc file and similar guides have shown a pattern of correcting links and clarifying instructions as underlying projects move or evolve.
• Maintaining up-to-date third-party URLs is a recurring theme in past PRs to avoid user confusion.
• No recent PRs have introduced code changes or modifications tying directly to this doc, reflecting a conservative approach to documentation edits.

Implications for Related Files

• Since only a doc file is changed, there are no direct implications on code or configuration files.
• Indirectly, this ensures future users and maintainers are guided correctly when working with OpenInference SDK integration in CrewAI observability.

Conclusion

This PR is a clean, focused, and necessary documentation update that correctly redirects users to the current OpenInference SDK repository location. There are no code quality concerns or violations of standards since the change is documentation-only.

No changes are required before merging. However, maintainers may optionally apply suggested wording improvements for clarity and consistency in future updates.
