Use versions of Task with Apple Silicon builds in tests

[per1234]

The unit and integration tests install various versions of Task.

The GitHub Actions macos-latest runner was recently changed from using x86 machines to Apple Silicon/ARM machines:

https://docs.github.com/en/actions/using-github-hosted-runners/about-github-hosted-runners/about-github-hosted-runners#standard-github-hosted-runners-for-public-repositories

Task is now built for both architectures. However, this was not done for the older versions of Task previously used for the tests. The runner architecture switch caused the tests to start failing spuriously on the macos-latest GitHub Actions workflow run jobs:

The obvious solution would be to pin the runner to the last x86 runner: macos-13 in the test runner workflows. However, GitHub phases out runners over time so this would not be a future proof solution. The chosen solution is to continue to use the Apple Silicon macos-latest runner and adjust the tests to use versions of Task for which an Apple Silicon build is available.

This was not possible for the integration test of the action's major version pinning capability. The reason is that a previous major version (2.x) must be used in this test in order to allow a consistent assertion, since the installed version would change over time if the latest major version was used. Apple Silicon builds are not available in the 2.x Task version series. For this reason, the integration test runner workflow is configured to skip that test on the macos-latest runner job. The Linux and Windows integration test runner jobs, as well as unit test (which is not constrained in this way due to using artificial tags data) will provide sufficient coverage for this capability.
