Enable eventwatcher replacement with key-pair value pattern

[khanhtc1202]

What would you like to be added:

Currently, the PipeCD eventwatcher value replacement only supports value under a simple query path like $.spec.xyz[1].yy... (only index and key name allowed). It would be better if we support key-value pair query as well.

Note: even better if we can support wildcard queries.

I close this issue because this is almost the same as [Support multiple value updates in EventWatcher] #5088
