Consistency Update

[Rustdude]

I did several small updates:

• Uniformely Renamed the code snippet tabs from "Windows", "Windows PowerShell", "PowerShell" to "Windows PowerShell"
• Uniformely renamed placeholders for addresses to "ADDRESS" (formerly sometimes named public key, very inconsistent"
• Fixed some linebreaks in PowerShell and Bash Code
• Added tabbed commands to the pchain_client documentration (to be consisitent with the "getting started" documentation)

I submitted this pull request with some important changes, that remained unfixed since two weeks. Are there any issues left to resolve before the request can be merged?
@manngayin612 noticed that I forgot to remove a test string, which is already resolved, are there any other issues open or do I need to completely reopen a pull request?

Additionally, I noticed, that the pull request failed some tests, is that the issue? Building and testing went all fine on my machine. Can you check why the automated tests failed? I noticed, that building and testing also runs fine in the GitHub Action, just the deployment to GitHub Pages fails, so I assume it could be a privilege issue? If so, maybe pull requests should not trigger a full GitHub Pages deploy script but only pass some automated tests.
