fix: don't ship an Ivy compiled library

Shipping as Ivy compiled is not recommended by Angular it it breaks
every library that has a dependency on ngx-bootstrap and that does
not ship as Ivy  compiled.

Enabling "fullTemplateTypeCheck" also works around an Angular compiler
problem regarding the `forRoot()` not working..
