Description

$this->changeColumn('website', null, ['default'=>'null'])

This should keep the column type as is but just makes it null-able. Right now you have to specify the current column type for 2nd parameter even if its not changing. I should make it so that passing empty string or null keeps it as is.

Its also finicky about 'default' being set to the string 'null' and not the actual value null.

Research direction

Start by locating the changeColumn() implementation and read how its second argument and the default option are handled. The change is done when an empty string or null preserves the existing column type, and a null default is handled consistently without requiring the string 'null'.
