hrx linter no longer validates or breaks down HRX where the root is a unit test

[Goodwine]

recombines all existing directory unit tests into HRX files reverting files breaking up on #1817

Fixes #1821

This PR does not seem to recombine directories that were broken up in the previous PR

[Goodwine]

The way I generated this PR:

git checkout main
git pull
git checkout -b hrx-500
git rebase --onto ${PR_SHA}~1 $PR_SHA hrx-500 #basically remove PR_SHA
git checkout main -- package.json tsconfig.json lint-spec.ts lib-js/lint-reporter.ts
# then changes to lint-spec.ts
_changesAfterPR=$(git diff $PR_SHA main)
_newChanges=$(git diff ${PR_SHA}~1 hrx-500)
diff <(echo "$_changesAfterPR") <(echo "$_newChanges")> # only diff was lint-spec.ts
npm run lint-spec -- --fix
git rebase main --interactive # and squashed any commits in between

Is there a particular directory that should not have been split? (the only non-splittable directory should have been HRX file that contains at most 1 unit test)

Look for input.scss files in that repo. Most of them should be unsplit.
And the fact that the unsplitting is not done is easy to see: the diff of this PR does not include any modified spec files.

git rebase main --interactive # and squashed any commits in between

This might have been the issue: it would have kept the split already done in main in between (as those files would not be modified in your branch).

I did the recombination work manually in #1827
