make help text not escaping newlines

[benjamin051000]

After running init.sh with default values, running make to see the help text does not appear to format the \ns correctly. I see this in my terminal:

❯ make
\n ------------------------------------------------------------- \n * watch, build and serve the documentation:  make run \n * only build:                                make html \n * only serve:                                make serve \n * clean built doc files:                     make clean-doc \n * clean full environment:                    make clean \n * check links:                               make linkcheck \n * check spelling:                            make spelling \n * check spelling (without building again):   make spellcheck \n * check inclusive language:                  make woke \n * check accessibility:                       make pa11y \n * check style guide compliance:              make vale \n * check style guide compliance on target:    make vale TARGET=* \n * check metrics for documentation:           make allmetrics \n * other possible targets:                    make <TAB twice> \n ------------------------------------------------------------- \n

It appears that using echo -e allows echo to escape newlines properly, but simply modifying the sp-files/Makefile to include this doesn't seem to fix the problem for me, as the generated Makefile is missing the modification. I'm not sure which file needs to be modified.

See #316 which has a better explanation of the issue.
