[v2compat] wrong param passed when param contains JSON

Environment

• KFP SDK version: master branch

Steps to reproduce

import kfp
from kfp import dsl
from kfp.components import create_component_from_func


@create_component_from_func
def test(json_param: str):
    print(json_param)


@dsl.pipeline(name='bug-json-param')
def my_pipeline(
    json_param: str = '{"a":"b"}',
    value: str = 'c',
):
    test(json_param).set_display_name('test1')
    test('{"a":"' + f'{value}' + '"}').set_display_name('test2')


if __name__ == '__main__':
    kfp.Client().create_run_from_pipeline_func(
        my_pipeline,
        arguments={},
        mode=dsl.PipelineExecutionMode.V2_COMPATIBLE,
    )

I got the following log for test2 task (task1 is expected).

{\"a\":\"c\"}

Expected result

{"a":"c"}

Currently FE implements a hack to workaround MLPipeline UI Metadata name conversion, we need to make sure to update frontend to remove the hack, once SDK has made corresponding change:

#5961 (comment)

@zijianjoy we might consider keeping the sanitization in UI permanently, because artifact naming convention changed when going to KFP v2. In v2, we will no longer sanitize artifact names automatically in SDK.

I see, thank you for confirming!
