redfish_config: fix support for boolean BIOS attributes

Backport of ansible-collections/community.general#189 to stable-2.9

Currently the redfish_config module will convert boolean bios_attribute_value
settings to strings (type str). This will cause BMCs expecting booleans to
error out.

This PR will change the default type of bios_attribute_value to 'raw' in order
to support strings and booleans.

Fixes #68251
