Documentation: Please update curl commands in nspawn-container article

[lwbt]

Describe the bug
Please update curl commands in nspawn-container article, after reading it once more and comparing the scripts I found a few differences because the other repo is a few commits behind.

To Reproduce
Steps to reproduce the behavior:

1. Go to https://github.com/unifi-utilities/unifios-utilities/tree/main/nspawn-container
2. Check "Step 2A: Configure the Container to use an Isolated MacVLAN Network" and compare links in text and code block
3. Scroll down to "Step 3: Configure Persistence Across Firmware Updates" and compare links in text and code block
4. A repository peacey/unifios-utilities is used instead of unifi-utilities/unifios-utilities

Expected behavior

• The links should be the same.
• No content outside this repo should be fetched with curl without telling the reader about it.

Additional context

• It could be a potential security issue in the future, but that's a bit far fetched, lets just say things should work as they are intended to be.
