update-description needs to update the call to DockerHub API

[zigarn]

Orb version

2.1.2

What happened

update-description doesn't work anymore.

According to documentation and docker/hub-feedback#2127 (comment) the endpoint is only working with JSON payload and not x-www-form-urlencoded anymore.

Expected behavior

Update command to use JSON payload.

Something like this could fix:

diff --git c/src/scripts/update-description.sh i/src/scripts/update-description.sh
index a1006c9..80cbb22 100644

 if [ $STATUS -ne 200 ]; then
   echo "Could not update image description"

But it depends on jq, which is available in cimg/* docker images but not necessarily in all executors.
