Fix Inconsistent URL Format in Getting Started tutorial

[codewithmide]

Fixes #11007

Description:

In this pull request, I address issue #11007, which relates to the inconsistent usage of URLs in the Wagtail documentation.

Changes Made:

I've standardized the URL format used throughout the documentation to consistently use "http://localhost:8000/" instead of "http://127.0.0.1:8000/". This change improves the clarity and user experience for individuals setting up a local development environment while following the documentation.

Please check the following:

• Do the tests still pass?[^1]
• Does the code comply with the style guide?
  • Run make lint from the Wagtail root.
• For Python changes: Have you added tests to cover the new/fixed behaviour?
• For front-end changes: Did you test on all of Wagtail’s supported environments?[^2]
  • Please list the exact browser and operating system versions you tested:
  • Please list which assistive technologies [^3] you tested:
• For new features: Has the documentation been updated accordingly?

Thanks for giving this a go @codewithmide. As far as I can see there was only one inconsistency where we use localhost instead of 127.0.0.1. I’d prefer we change that one spot rather than everything else, unless we have a good reason?

I believe we chose 127.0.0.1 because that’s what the runserver command we use displays in its output.

Yeah that's true, I have made the change now. Thank you for the correction.
