Bump required version of Module::Runtime to get fix for detecting load failures (RT#92770, RT#86394)

However, this version of MR also fixes its interpretation of version=undef,
which is what was what our () for the 'version' argument was being turned into
in scalar context. So, we now have to bypass prototypes when we call these
functions (RT#92791).
if we have pod appearing before code, ensure it does not change line numbers
bump version to 2.1203
