Previously using make bump to bump a version did not also update all of
the test cases and documentation to reflect the new version. This patch
updates the make bump tasks call HOLOS_UPDATE_SCRIPTS=1 scripts/test to
keep the test cases and documentation in sync with the new version.
PROBLEM:
The "Hello Holos" tutorial has hardcoded code blocks and hasn't been
updated to use the automated testscript workflow.
SOLUTION:
* Create a test for the Hello Holos tutorial.
* Create a testscript for the Hello Holos test.
* Update the Hello Holos MDX file to load in data from the testscript directory.
OUTCOME:
The code content in the Hello Holos tutorial now comes directly from the
testscript workflow.
