Update ch12-05 PowerShell note

[ryan-willis]

Simplifies and slightly clarifies the PowerShell commands in Chapter 12.5.
Also made it a blockquote to make it easier to skip if it doesn't apply to the reader.
(EDIT: added "cmdlet" to the dictionary for https://docs.microsoft.com/en-us/powershell/scripting/developer/cmdlet/cmdlet-overview?view=powershell-7)

PS Command:

$Env:CASE_INSENSITIVE=1; cargo run to poem.txt

Output:

    Finished dev [unoptimized + debuginfo] target(s) in 0.01s
     Running `target\debug\minigrep.exe to poem.txt`
Are you nobody, too?
How dreary to be somebody!
To tell your name the livelong day
To an admiring bog!

Then:

Remove-Item Env:CASE_INSENSITIVE; cargo run to poem.txt

Output:

    Finished dev [unoptimized + debuginfo] target(s) in 0.01s
     Running `target\debug\minigrep.exe to poem.txt`
Are you nobody, too?
How dreary to be somebody!

Thanks for this! I am a newbie at powershell, and always just opened a new shell, heh.

Could you also remove the blockquote please? When we turn the book into printed form, we won't want it, and so this is a well-intentoned change but not one that I can accept.

[steveklabnik]

can you add newlines above and below both of these codeblocks, so that the style is similar to what's removed?

[ryan-willis]

Done 👍

@steveklabnik rebased (squashed) and resolved conflicts

[steveklabnik]

Looks great, thanks!
