grip trainer alias'

BUR #26953 has been approved by @nonamethanks.

create alias hand_grip_strengthener -> grip_trainer

common names to refer to this piece of exercise equipment

in the how to tag thread some of us thought of "(hand) grip strengthener" not realizing this already had a tag in grip trainer

Those two aliases are redundant with one another. If you type grip_str after this is approved, only one will show up because each tag can only appear once in the autocomplete.

fixed
