Add a Click to Copy Button for Code Blocks in docs

Is your feature request related to a problem? Please describe:
It is important to have a "copy" button available on code blocks in the documentation. This will allow users to easily copy the entire code without accidentally leaving any important parts behind.

Describe the solution you'd like:
We will use JavaScript to implement the copy functionality throughout the complete documentation, allowing for a specific code block to be copied.

Steps to reproduce:

• Go to the developer documentation website.
• Check for any code block

Screenshot:

Start at the developer documentation website linked in the issue and inspect how its code blocks are rendered. Review the existing pull request linked to this issue before making changes. Done means code blocks throughout the documentation provide a way to copy the complete block.
