Looks very good, thank you!

I guess pwsh is nowadays called powershell? I never used powershell I have no clue 😬 (I can hardly believe it is not executed via pwsh on linuxerian OSes).

And this certainly renders it useless , 2404 is ages old already. Whatever, that does not matter for this PR.

Hmm, not supporting Ubuntu 24.04 makes no sense.
And/but they support MacOS 14.6.1 (latest latest) via Homebrew? This is strange, why is it not community-supported on Ubuntu?

Hmm, in comparsion the new install method takes quite a lot of space; maybe hide some of the sub-points by just linking to the documentation on your installers project and list only the one or two major things explicitly.

Indeed, PowerShell 7 was initially known as "PowerShell Core" following its complete overhaul in version 6. It's distinct from Windows PowerShell 5.1, which is reflected in its binary file name pwsh.exe for Windows, allowing it to run alongside the older version. Similarly, Unix systems use the pwsh name for their binaries.

Despite these changes, for backward compatibility, documentation and markdown language tags often simply refer to it as powershell. For instance, the Microsoft documentation on including code adheres to this convention. GitHub's syntax highlighter, powered by linguist, recognizes pwsh as a synonym for powershell, which might have led to the oversight in updating your documentation. Apologies for any confusion caused.

And this certainly renders it useless , 2404 is ages old already. Whatever, that does not matter for this PR.

Regarding Ubuntu releases, the designation of the latest LTS version is finalized with the first .1 point release, which happened on August 29th, 2024. Firms like Microsoft usually await this milestone before incorporating the new LTS version into their lineup of supported OS. Technically, Microsoft has prepared much of the necessary infrastructure. I've also pitched in with a small update for the Dev Container features, so we can expect full support to roll out soon. :-)

It's worth noting that the term "supported" doesn't imply any malfunction; it simply refers to the availability of commercial support, such as contacting Microsoft for assistance when something doesn't work as anticipated. I know in German we usually think about "etwas wird unterstützt" a little differently, like "läuft nicht".

I've taken this into account in the latest update. Could you please review it again?
