console/postgres: fix broken table view when clicking on inherited tables

### Description
- Fixes https://github.com/hasura/graphql-engine/issues/6926
- This is to resolve the issue where inherited tables get listed into the array that's used to filter off partitions.
- In the check, we compare if the partition's parent is a "partitioned table" or not before adding to the filter array.

### Steps to verify
- Create the following tables on a postgres db
```SQL
CREATE TABLE cities (
id SERIAL PRIMARY KEY,
name       text,
population real,
elevation  int     -- (in ft)
);

CREATE TABLE capitals (
state      char(2) UNIQUE NOT NULL
) INHERITS (cities);
```
- Navigate to the data tab, and click on the datasource > schema, and verify that both `cities` and `capitals` are present.
- Click on `capitals` and see if it loads properly.
- Create the following table and its partitions
```sql
CREATE TABLE measurement (
    city_id         int not null,
    logdate         date not null,
    peaktemp        int,
    unitsales       int
) PARTITION BY RANGE (logdate);

CREATE TABLE measurement_y2006m02 PARTITION OF measurement
    FOR VALUES FROM ('2006-02-01') TO ('2006-03-01');

CREATE TABLE measurement_y2006m03 PARTITION OF measurement
    FOR VALUES FROM ('2006-03-01') TO ('2006-04-01');
```
- Verify that the data tab nav does not show `measurement_y2006m02` and `measurement_y2006m03`
