ci(workflows): update runner to oracle-vm-24cpu-96gb-x86-64

[chlins]

This pull request updates the GitHub Actions workflow configurations to use a more powerful runner for all major jobs. Instead of running CI, build, test, and release jobs on the default Ubuntu runners, these workflows will now use an oracle-vm-32cpu-128gb-x86-64 runner, which should provide significantly more CPU and memory resources for faster and more reliable execution.

Workflow runner changes:

• All CI jobs in .github/workflows/CI.yml now use oracle-vm-32cpu-128gb-x86-64 instead of ubuntu-latest for unit tests, API tests, LDAP tests, offline tests, and UI unit tests. [1] [2] [3] [4] [5] [6]
• The build package workflow in .github/workflows/build-package.yml now uses oracle-vm-32cpu-128gb-x86-64 instead of ubuntu-22.04.
• The conformance test workflow in .github/workflows/conformance_test.yml now uses oracle-vm-32cpu-128gb-x86-64 instead of ubuntu-latest.
• The release publishing workflow in .github/workflows/publish_release.yml now uses oracle-vm-32cpu-128gb-x86-64 instead of ubuntu-22.04.Thank you for contributing to Harbor!

There are ubuntu runners with more memory as well, why do we need to change the OS, as this can cause some complications?

There are ubuntu runners with more memory as well, why do we need to change the OS, as this can cause some complications?

These runners were provided by CNCF enterprise, since if we can choose more CPU & Memory and if the CI can pass, that means no complication issue, do we need to care the OS?
