Allow to use commands within InputRule and PasteRule

[philippkuehn]

With this PR we can now use commands, chain and can within input rules and paste rules as known from command methods.

new InputRule({
   find: someRegex,
-  handler: ({ state, range, match }) => {
+  handler: ({ state, range, match, commands, chain, can }) => {
     // ...
   },
})
