refactor(migrations): remove rxjs usage within static queries migration (#38657)

rxjs was only used within one location within the static queries migration to workaround
a previous limitation that schematics could not directly use a promise.  However, promise
support has been available since 8.0.  This change removes the observable promise wrapping.
It also removes an any cast that was previously needed to workaround rxjs version mismatches
during compilation.
