[actions] point cargo-deny action at our fork to mitigate tar failure (…

…MystenLabs#9862)

## Description 

Attempt to fix the error seen in
https://github.com/MystenLabs/sui/actions/runs/4515249036/jobs/7952315116?pr=9814
by using our [forked
version](MystenLabs/cargo-deny-action@ca3520a)
of the cargo-deny action with the fix.

I also submitted a [PR in the original
repo](EmbarkStudios/cargo-deny-action#62) so we
can go back to using it after the fix is in place.

## Test Plan 

Ran successful cargo-deny with our fork in
https://github.com/MystenLabs/sui/actions/runs/4515503791/jobs/7953092763
