fix: remove stray $ character

Removed a stray $ character that was causing issues when copying and pasting the code into the terminal.

Description

The commit removes a stray $ character from the code that was causing problems when copying and pasting the script into the terminal.

Motivation and context

This change is required because the stray $ character was causing an issue when users attempted to copy the code into the terminal. When copied directly, the $ symbol was interpreted incorrectly by the terminal.

How has this been tested?

I tested the change by:

Copying and pasting the code into a terminal after the $ character was removed.
Verifying that no errors occur during the paste operation and the code runs successfully.
Ensuring that the terminal accepts the pasted code without unexpected behavior.
Testing was done in a local environment on PhpStorm terminal.

Screenshots (if appropriate)

I've given it some thought and concluded that it's fine. The $ symbol is traditionally used to indicate "as a user, not root," but in this context, it’s not worth disrupting the copy-paste functionality of GitHub command-line examples.

Could you please apply the same modification to docs/content to ensure consistency?

Thanks in advance!
