Configurable XML tagging pre-prompt

[gsproston-scottlogic]

Usually the XML tagging defence is paired with a pre-prompt, just like RSE. Add this in, and make it configurable.

An example can be seen here: https://learnprompting.org/docs/prompt_hacking/defensive_measures/xml_tagging

@asaha-scottlogic Not sure what you mean by "cannot get rid of it". You cannot leave the box empty, that's by design, and you see a warning message when you try (although admittedly not the clearest warning in the world):

You can deactivate the defence if you don't want it.

As discussed in the daily, this might need the .env file updating.
