fix: remove shell prompt symbols from installation commands

[schacherle]

Changes

Removes the leading $ shell prompt symbol from bash code blocks in the installation guide. The $ was being included when users clicked the copy-to-clipboard button, so pasted commands either failed outright or required manually stripping the prompt character first.

Also fixes a stray ```bash $ fence typo on the webhook-cert setup block.

Pull request overview

This PR updates the documentation command snippets to remove the leading $ shell prompt character so the copy-to-clipboard behavior produces directly runnable commands. It also fixes a malformed code fence in the installation guide.

Changes:

• Removed leading $ prompt symbols from shell command examples to prevent copy/paste failures.
• Fixed an incorrect code fence (bash $ → bash) in the webhook-cert setup block.
• Applied the same command-format cleanup to a few additional docs pages containing kubectl examples.

Thanks for bringing it up. I totally understand the copy feature being useless here is bad. On the other side, the "$" is usually used when you have a command and output. So the copy would copy the command output as well, wouldn't it? If it's like that, we would actually need to separate the command and the output to make it useful.

Hi @schacherle ,

As mentioned above, could you update it to separate the command from its output? This would allow us to remove the “$” from the command without causing any issues.

I've updated it to align with https://kubernetes.io/docs/contribute/style/style-guide/#don-t-include-the-command-prompt, separating the prompt from the output.
