Add the fishing rod slot 28 to the Weapon Imbue

[ObiWahn86]

Is your feature request related to a problem? Please describe.
Before Dragonflight I used an icon to warn me that I hadn't applied a lure to my fishing rod. This was possible because the fishing rod was equipped in the weapon slot. After DF that doesn't work anymore because I can't select the new fishing rod slot for monitoring.

Describe the solution you'd like
I'd like to have the fishing rod slot (number 28) added to "Weapon slot to monitor" in addition to main hand and off hand.

Describe alternatives you've considered
I considered checking for a buff but the lure on the fishing rod isn't shown as buff.
