docs(synthetics_step_monitor): moved list of valid values to correct argument

[sxchx]

Description

Noticed that a list of valid values for the type argument under the steps nested block were incorrectly placed under the values argument. Have moved the list to be under the type argument. Also corrected a capitalised O to lowercase.
