fixes: CNVS-29208
as part of https://gerrit.instructure.com/77427
we created a remove_brand_dir! method but in code
review decided it would be better to call it
remove_scss_dir! but did not catch renaming
this one spot where didn't change it
test plan:
go to theme editor
make change and preview 3 different times
it should not have a page error
