A few number theory commands in Oscar

[Asconik]

1. The ramified_primes command does not work on its own, only by entering Hecke.ramified_primes:
   https://oscar-system.github.io/Oscar.jl/stable/Hecke/orders/orders/#ramified_primes-Tuple{NfOrd}

2. Same issue for isprincipal_fac_elem, gotta enter Hecke.isprincipal_fac_elem:
   https://oscar-system.github.io/Oscar.jl/stable/Hecke/orders/ideals/#isprincipal_fac_elem-Tuple{NfOrdIdl}

3. The documentation for the Order method
   https://oscar-system.github.io/Oscar.jl/stable/Hecke/orders/orders/#Order-Tuple{AnticNumberField,%20Vector{nf_elem}}
   is incorrect:

• It needs the number field as first argument before all the rest
• The command includes the keyword "cached", but the description says "isbasis" (but "isbasis" is also a keyword? Are there actually three keywords in all?)

4. In the following ideal method
   https://oscar-system.github.io/Oscar.jl/stable/Hecke/orders/ideals/#ideal-Tuple{NfOrd,%20fmpz_mat}
   why are "check" and "x_in_hnf" not keywords? Like in the Order method in 3)

Thanks for the report.
