Support angular 20

[el-davo]

When updating to angular 20 we are getting this error

./node_modules/.pnpm/@busacca+ng-pick-datetime@13.0.1_ybbipimkjqebb6ivrl2ctw2ysi/node_modules/@busacca/ng-pick-datetime/fesm2020/busacca-ng-pick-datetime.mjs:4303:17-31 - Error: export 'PortalInjector' (imported as 'PortalInjector') was not found in '@angular/cdk/portal' (possible exports: BasePortalOutlet, CdkPortal, CdkPortalOutlet, ComponentPortal, DomPortal, DomPortalOutlet, Portal, PortalHostDirective, PortalModule, TemplatePortal, TemplatePortalDirective)

For anyone who comes across this. It looks like this library is unmaintained, there is a fork here with a similar issue open
