Scenario: The icon needs to update on several places on dokan

[MdAsifHossainNadim]

@mrabbani Vhai, need to relevant ui's for new issues. @shashwatahalder01 Vhai, If anything is required or if you have any suggestions for us, then feel free to inform us.

@MdAsifHossainNadim, @mrabbani, It would be better if we could introduce a new color pallet that is aligned with the latest dokan logo

Here is the Design Link. Please have a look.

@tuhin480 Vhai, we need to make consistent between existing banner & updated logo. Here is the preview after updating logo.

I think It will be better if we added some shadow or spaces on left/bottom side in this banner image. (as like as previous)

We need to update wp org's banner & icon logo's as per latest update.
