Fix typo in 'Roentgenologist' alias

[tjasz]

Description, Motivation & Context

The current alias "Rontegenologist" appears to be a typo, intended to be "Roentgenologist". The word roentgenology is derived from the name of Wilhelm Röntgen, usually transliterated as Roentgen. This PR corrects the typo to give the alias its proper name.
