Cosmos/FTS: enable full text search and vectors on collections once Cosmos supports wildcards in paths for their indexes and container policies

Currently FTS and vectors don't support wildcards when defining index policy and container policy:

https://learn.microsoft.com/en-us/azure/cosmos-db/gen-ai/full-text-search

So when we build container / index paths we can't do this the right way for entire collection. Only thing that works now is to define them individually for each element:

/Owned/Collection/0/MyFTSProperty
/Owned/Collection/1/MyFTSProperty
etc.

once wildcards work we will be able to do: /Owned/Collection/[]/MyFTSProperty
