Enable automation of MATLAB tests (#59)

* Add usage of `matlab-actions/run-tests` to test automation

* Set up MATLAB prior to running tests in test action

* Move MATLAB testing to separate job

* Specify MATLAB version

* Checkout before MATLAB tests

* Resolve test failures

* Update assertion

* Temporarily update test action to run against all supported MATLAB versions

* Leverage `testCase.assumeTrue` to skip tests in certain environments

* Update tFormatCode `assumeTrue` condition

* Update tFormatCode isApplicable check to check Java Swing again

* Return isApplicable check to checking for the testing environment

* Fix message text
