Remove temporary cache cleaning fix from OS smoke tests

[npepinpe]

Description

This PR removes the temporary cache cleaning actions from the OS smoke tests. It doesn't seem to be doing much at this point, as we still regularly run into issues with it. Let's go with the "standard" cache action and start again when we see issues.

Definition of Done

Not all items need to be done depending on the issue and the pull request.

Code changes:

• The changes are backwards compatibility with previous versions
• If it fixes a bug then PRs are created to backport the fix to the last two minor versions. You can trigger a backport by assigning labels (e.g. backport stable/1.3) to the PR, in case that fails you need to create backports manually.

Testing:

• There are unit/integration tests that verify all acceptance criterias of the issue
• New tests are written to ensure backwards compatibility with further versions
• The behavior is tested manually
• The change has been verified by a QA run
• The impact of the changes is verified by a benchmark

Documentation:

• The documentation is updated (e.g. BPMN reference, configuration, examples, get-started guides, etc.)
• New content is added to the release announcement
• If the PR changes how BPMN processes are validated (e.g. support new BPMN element) then the Camunda modeling team should be informed to adjust the BPMN linting.

(refusing to allow a GitHub App to create or update workflow .github/workflows/os-smoke-test.yml without workflows permission)

Yeah this is a permissions topic. If we want it to be able to backport changes to workflow files, then we need to explicitly give it the permission to do so. We could consider that 🤔 What do you think? @npepinpe
