command/jsonstate: fix inconsistency with resource address (#24256)

Browse Source 
* command/jsonstate: fix inconsistency with resource address

Resource addresses in state output were not including index for
instances created with for_each or count, while the index was appearing
in the plan output. This PR fixes that inconsistency, adds tests, and
updates the existing tests.

Fixes #24110

* add tests showing expected prior state resource addressing
* added example of show json state output with modules
