erp5: jupyter.enable is boolean, not string

When originally in 0a446263 (ERP5 and Jupyter integrated together) I added
Jupyter support into ERP5 the parameter for whether to enable/disable it was
declared as boolean in JSON schema but processed as string in instance code,
this way preventing usage of real JSON's boolean.

Fix it.

(also fixing up software/slapos-master/ which copied the files for play in 87d13789)

/cc @rafael for slapos-master change.

Thanks for fixing our side too.

I will check again if we could drop the existing variations.
