Remove invalid parameters for `InputDecoration.collapsed`

InputDecoration.collapsed invalid parameters floatingLabelBehavior and floatingLabelAlignment are deprecated.

InputDecoration.collapsed constructor is used to create a minimal decoration without a label.

The parameters floatingLabelAlignment and floatingLabelBehavior have no effect because an input decoration created using InputDecoration.collapsed has no label.

To migrate, remove usage of floatingLabelBehavior and floatingLabelAlignment parameters when calling the InputDecoration.collapsed constructor. Those parameters had no effect.

Code before migration:

InputDecoration.collapsed(
  hintText: 'Hint',
  floatingLabelAlignment: FloatingLabelAlignment.center,
  floatingLabelBehavior: FloatingLabelBehavior.auto,
),

Code after migration:

InputDecoration.collapsed(
  hintText: 'Hint',
),
