The "direction" argument of abjad.Staccato() is not producing the expected output

[gilbertohasnofb]

The direction argument of abjad.Staccato is not producing the expected output while the same argument of abjad.Articulation works as expected:

import abjad
articulation1 = abjad.Articulation('staccato', direction=abjad.Up)
articulation2 = abjad.Staccato(direction=abjad.Up)
print(articulation1.direction)  # => Up
print(articulation2.direction)  # => Up
note1 = abjad.Note("c'4")
note2 = abjad.Note("c'4")
abjad.attach(articulation1, note1)
abjad.attach(articulation2, note2)
staff = abjad.Staff([note1, note2])
abjad.show(staff)

Confirmed that this is a bug:

staff = abjad.Staff("c'4 c'4")
articulation = abjad.Articulation('staccato', direction=abjad.Up)
abjad.attach(articulation, staff[0])
staccato = abjad.Staccato(direction=abjad.Up)
abjad.attach(staccato, staff[1])

abjad.f(staff)
\new Staff
{
    c'4
    ^ \staccato
    c'4
    \staccato
}

abjad.Articulation respects direction while abjad.Staccato does not.

Will open a PR to merge into main after checking other articulation classes.
