I don't know if anything has changed with the configuration of the roads and access following the construction of the new Terminal 2. However, in the past what I saw was that if you simply kept walking along the curb outside the airport building (the taxi pick-up/drop-off area) (along in the direction rightward if you are facing the terminal building from the outside), it curved around a bit, and you could walk on the sidewalk along the road that continues at right angles to the terminal building, and then on to road that crosses it until the Taj. Or cut across the Uber parking lot and employee cafeteria space and save a few steps. Relatively easy, no worry of needing to dodge high-speed traffic on the roads or anything like that, and relatively flat surfaces that you can rolled luggage along on.

But caveat - I know the roads have changed quite a bit now that T2 is open, so I don't know if the same easy walk is possible now.
