ci(connector-corda): fix insufficient disk space errors

[petermetz]

We have the disk clean-up in the CI off by default because it takes a few
minutes to perform and most jobs don't need it, but for Corda it seems
necessary because our tests started failing with the message below
(lines wrapped to make sure we don't run over the 100 character limit
for the git commit message)

• Rebased onto upstream/main branch and squashed into single commit to help maintainers review it more efficient and to avoid spaghetti git commit graphs that obfuscate which commit did exactly what change, when and, why.
• Have git sign off at the end of commit message to avoid being marked red. You can add -s flag when using git commit command. You may refer to this link for more information.
• Follow the Commit Linting specification. You may refer to this link for more information.
