[ENH]: defaults tests:vm to not be excluded

[joshdunnlime]

vm tests are now include, but explicity excluded in standard cicd test suite. test-est still picks these vm tests up as before.

Reference Issues/PRs

Fixes #682

What does this implement/fix? Explain your changes.

Add an expilicity skip_vm parameter. vm tests are skipped in the standard CI test suit. Inverting this allows vm tests to run locally. In CICD, this is turn back on to skip vm tests in the standard suite. These vm tests should still be picked up in the test-est CICD tests.

Does your contribution introduce a new dependency? If yes, which one?

No

What should a reviewer concentrate their feedback on?

Do this still preserve CICD behaviour? Does this allow you to run a tests:vm test locally, without a workaround?

Did you add any tests for the change?

No

Any other comments?

• The PR title starts with either [ENH], [MNT], [DOC], or [BUG]. [BUG] - bugfix, [MNT] - CI, test framework, [ENH] - adding or improving code, [DOC] - writing or improving documentation or docstrings.

For new estimators

• I've added the estimator to the API reference - in docs/source/api_reference/taskname.rst, follow the pattern.
• I've added one or more illustrative usage examples to the docstring, in a pydocstyle compliant Examples section.
• If the estimator relies on a soft dependency, I've set the python_dependencies tag and ensured
  dependency isolation, see the estimator dependencies guide.
