Cannot edit, update or delete rules if their name ends in a question mark (?)

[mattrayner]

So, interestingly, if you have a rule named show_lords_ineligibility_banner? and you try to edit, update, or delete that rule, in the UI, you get a 404

Because the link generated for an edit or delete is:
/groups/parliament/features/show_lords_ineligibility_banner?/delete

Meaning the router breaks

I'll look at either opening a PR to fix this, or asking one of my team to 👍
