Upgrade Oracle docker image for testing to oracle-free 23

[takezoe]

Description

Upgrade Oracle docker image for testing from oracle-xe 11 to oracle-free 23.

This will also allow us to run Oracle connector test cases on Apple Silicon Mac as oracle-free has arm64 image while oracle-xe doesn't.

Release notes

(x) This is not user-visible or is docs only, and no release notes are required.

It seems flakier than before.

Hmm... Extending the startup timeout could improve stability? Let me try.

This pull request has gone a while without any activity. Ask for help on #core-dev on Trino slack.

Extending the startup timeout was effective. Oracle test cases are now much more stable.

Could you add a temporary commit to run stress tests, similar to #26587?

[wendigo]

Upload test results have failed due to conflict. Tests alone look fine :)

[takezoe]

Yeah, Maven Tests passed without errors in all attempts:
https://github.com/trinodb/trino/actions/runs/18166480223/job/51710161057?pr=26573

I will remove the test commit and clean up the PR.

Thanks! I think we can handle #5901 as a follow-up.
