angular.json styleext option was replaced with style

[Jane Sandberg]

When I tried to run the Angular generator to create a new component, I got the following error:

````
Schematic input does not validate against the Schema: {"prefix":"eg","styleext":"css","path":"src/app/staff/cat","module":"z3950","name":"z3950-services","project":"eg"}
Errors:

  Data path "" must NOT have additional properties(styleext).
````

Looks like this changed with version 9 of ng-cli: https://github.com/angular/angular-cli/releases/tag/v9.0.0 (it's the second item under "breaking changes").

"styleext" in angular.json should now be "style".

Branch coming up!

Here is the branch: https://git.evergreen-ils.org/?p=working/Evergreen.git;a=shortlog;h=refs/heads/user/sandbergja/lp1995211-styleext

[Galen Charlton (gmc)]

Straightforward, so I've tested and pushed down to rel_3_9. (Leaving it at just master was probably sufficient, since one really ought to be starting from the main branch if one is adding a new component, but just in case anybody's IDE would care while working in back branches...)

Thanks, Jane!
