Fixed part of Issue - #19100, changed documentation for axisartist

[aflah02]

Issue - The axisartist.axis_artist docs page has a typo: ax.axis["bottom"].major_ticks.set_ticks_out(True) should be ax.axis["bottom"].major_ticks.set_tick_out(True) (remove 's' after 'tick' in 'set_tick_out')
Fixed it by removing the s
closes #19100
