Remove --disable-instruction-limit from the Playground mode

[reeelix]

In Playground mode, only one instruction is executed at a time. Therefore, applying a limit to the number of executed instructions doesn't make sense there.

Since the option is hidden in the CLI help and will rarely be necessary, this doesn't make to much of an impact and can be considered very non-urgent.

not urgent

Yeah, this option could be removed from the sandbox mode. But as this is not urgent, because it is hidden by default and because the implementation could be a bit of a pain (probably requiring a new argument group) this issue will not be actively worked on for now.

Idea how this could be done. As there is now a new argument group (CheckLoadArgs) this '--disable-instruction-limit' argument could be moved there. This way the argument would no longer applicable to the playground subcommand.
