Update createDialog function to allow custom buttons

At the moment the createDialog function only allows for ok and cancel buttons. This is hardcoded into the function itself:
__glassAppController.Glass.getCoreSvc('.Dialog').createDialog:
 

createDialog(e) {
   const t = (0,
   a.default)("dialog");
   (e = Object.assign(Object.assign({}, e), {
       id: t
   })).callback && "object" == typeof e.callback && Object.keys(e.callback).length > 0 && Object.values(e.callback).filter(e=>e && "function" == typeof e).length > 0 && (this.registerCallbackForButton(e, "close", t),
   e.buttons && Array.isArray(e.buttons) && ["ok", "cancel"].forEach(n=>{
       (e.buttons.includes(n) || e.buttons.filter(e=>e.defaultId === n).length > 0) && this.registerCallbackForButton(e, n, t)
   }
   )),
   this.store.addDialog(e)
}

This means running the function:
__glassAppController.showMessage(
  '<span style="font-size:30pt;color:black">hello!</span>'
  , 'Message Title'
  ,'info'
  , ["ok","cancel","test"]
  , '300px'
  , function(a){console.log(a)}
  , true
)

will result in a message box with three buttons:
"Cancel", "__NOT_TRANSLATED__(undefined)", "OK"

with the middle button not performing any action when called.

Please add something like after the e.buttons...forEach:
e.buttons.filter(btn=>!["ok","cancel"].includes(btn??btn.name)).forEach(btn=>{
   this.registerCallbackForButton(e, btn[userLocale??default], t)
})

This would allow extension authors to pass custom buttons to createDialog:

__glassAppController.showMessage(
  '<span style="font-size:30pt;color:black">hello!</span>'
  , 'Message Title'
  ,'info'
  , ['ok','cancel',{"name":"test","default":"test","en-us":"US TEST","en-uk":"Brittest","en-au":"Throw another shrimp on the barbie!"}]
  , '300px'
  , function(a){console.log(a)}
  , true
 )

Without this extension authors need to write their own functions to add dialogs, which means that updates to Cognos will mean more maintenance on the author's side.
