Remove prefix from shell code snippets

Not sure what others think about this.

From my POV, having the $ is a pain if you want to copy / paste commands from the shell code snippets.

This is indeed something of value 👍

$ is nicer visually, because one sees, where a command starts, but you are right that it is not so nice when copying. I would not mind removing them, but I just stumbled across this piece of Antora docs:

Console blocks
The default UI also adds a clipboard button to all console blocks. A console block is either a literal paragraph that begins with a $ or a source block with the language console.

The script provided by the default UI will automatically strip the $ prompt at the beginning of each line and join the lines with &&.

https://docs.antora.org/antora-ui-default/code-blocks/#console-blocks

It is a feature of default Antora UI, so it may or may not work in the same way in Camel custom UI.
We should perhaps try to switch from [source,shell] to [source,console]

Yes, there is no copy button support unfortunately apache/camel-website#1137.

Good to know. Let's get rid of the dollars then.
