update service principals redirect

Description

🎫 IPL-8702 https://hashicorp.atlassian.net/browse/IPL-8702

A redirect that was previously working no longer is. Notably there was a redirect fro the source URL to a destination that then was used as a source for another redirect. For whatever reason chaining the redirects in this way does not work (I don't know if this is supposed to be supported or not), so this PR updates the first redirect so the destination matches the second redirect.

Requested review scope:

• Content touched by the PR only (typos, clarifications, tips)
• Code test (command and code block changes)
• Flow and language near changes (new/rearranged steps)
• Review everything (rewrites, major changes)

Review urgency:

• ASAP (bug fixes, broken content, imminent releases)
• 3 days (small changes, easy reviews)
• 1 week (default)
• Best effort (very non-urgent)

All updates:

I have:

• Verified that all status checks have passed
• Verified that preview environment has successfully deployed
• Verified appropriate label applied (hcp + product name)
• Added all required reviewers (code owners and external)

Content checklist (optional)

Please do these things before requesting a review. I have:

• Made any associated code repositories public
• Added the hashicorp-education/teamName to any additional code or example repos as repo admin
• Added redirects for any moved or removed pages
• Spell checked the tutorial(s)
• Followed the unified style guide
• Linted code snippets (Details per language here)
• Checked the steps for completeness (no steps are implied or hidden)
• Looked at the local or vercel build and checked each new or changed page for:
  • display on the product curriculum page
  • callout box formatting
  • code block highlighting
  • right-hand navigation
  • next and back buttons
  • URL path

This redirect goes to the page service-principals is also meant to go to.
