lists/contracts/shield: fix missing dev-detect

There was invalid option name specified. It is not 'dev-detect' but
'dev_detect' as options are accessed directly and thus they use syntax
consistent with variable names where dash is not allowed.

This also indents code the same way as in rest of the lists.
