Mismatch of client type for 07-celestia clients

[crodriguezvega]

For 07-celestia light clients the stored ClientState is of type 07-tendermint, so queries like /ibc/core/client/v1/client_states/07-celestia-{n} will return a client state whose client type is 07-tendermint. This might be a bit confusing and/or undesirable. We should discuss if this is acceptable or if we should do something about it (and what in that case).

Potential workaround discussed in engineering call: override the client state stored with a 07-celestia client state after calling the base 07-tendermint client functions.
