Pin Conan revisions correctly (#6828)

* Pin Conan revisions correctly

Conan dependencies are not pinned correctly. This means we're
pulling in a newer onetbb recipe that no longer has a shared
library option.

Following other examples of how to pin revisions with cmake
for conan v1, we correctly pin the expected revisions.

Longer term we should look into
- upgrading to conan v2
- defining the conan config separately from cmakelists.txt
- understanding the need for disabling onetbb shared library support

but for the purposes of reviving CI, this will be sufficient.

* Fix macos CI builds
