perf(query): remove transactions for queries (#8614) 
# Which Problems Are Solved

Queries currently execute 3 statements, begin, query, commit

# How the Problems Are Solved

remove transaction handling from query methods in database package

# Additional Changes

- Bump versions of `core_grpc_dependencies`-receipt in Makefile

# Additional info

During load tests we saw a lot of idle transactions of `zitadel_queries`
application name which is the connection pool used to query data in
zitadel. Executed query:

`select query_start - xact_start, pid, application_name, backend_start,
xact_start, query_start, state_change, wait_event_type,
wait_event,substring(query, 1, 200) query from pg_stat_activity where
datname = 'zitadel' and state <> 'idle';`

Mostly the last query executed was `begin isolation level read committed
read only`.

example: 

```
    ?column?     |  pid  |      application_name      |         backend_start         |          xact_start           |          query_start          |         state_change          | wait_event_type |  wait_event  |                                                                                                  query

```

The amount of idle transactions is significantly less if the query
transactions are removed:

example: 

```
    ?column?     |  pid  |      application_name      |         backend_start         |          xact_start           |          query_start          |         state_change          | wait_event_type | wait_event |                                                                                                  query
