Update pricing url with ref and refAction params [GRO-282] (#24339)

## Description
In order to better attribute upgrade sources, we are adding two params -
`ref` and `refAction` to the existing pricing url.
The `ref` will be "Docs" and the `refAction` will be the particular docs
page from where the pricing url click is originated.
