[BUG] Bridge matter idl generation

[mustafayuce33]

Reproduction steps

If you take a look at this line;
https://github.com/project-chip/connectedhomeip/blob/master/scripts/py_matter_idl/matter_idl/generators/bridge/__init__.py#L90

It checks if the definition is nullable. But it should check if it is optional I guess. So this line should be as follows

if definition.is_optional:
        cType = '::chip::Optional<{}>'.format(cType)
