Oracle test starts failing (listener refused the connection)

[javiertuya]

Latest Combined dependency updates (2023-11-25) #100 ran successfully on main: https://github.com/giis-uniovi/qacover/actions/runs/6987984114, Suddenly some unrelated udpates of other components started failing the oracle job. After rerunning the above update, it failed too. It seems to be a problem with the docker image, memory resources, etc...

It seems to be fixed after migrating oracle to 21.3.0 cbec5fe
