Update GitHub workflow to run tests in specific directory

The commit modifies the GitHub action workflows to deal with dependencies and run tests in the 'libs/text-2-measurements' directory. This specifically targets the correct location ensuring that npm operations, install and test, are executed in the necessary directory and not at an erroneous relative path.
