[Enhancement]: Predicate operators in REST for GraphQL parity

## Graphql currently supports:

- `in`: checks if a column's value exists in a specified set of values.
- `contains`: finds a fragment anywhere in a string
- `notContains`: excludes strings containing a fragment
- `startsWith`: matches the beginning of a string
- `endsWith`: matches the end of a string

## What?

Bring REST in parity with GraphQL.

## Why?

REST is our most popular endpoint type.

## How?

Here are the SQL `WHERE` clause equivalents for each `$filter` expression:

### `$filter=Category in ('Books', 'Movies', 'Games')`

```sql
WHERE Category IN ('Books', 'Movies', 'Games')
```

### `$filter=contains(Name, 'son')`

```sql
WHERE Name LIKE '%son%'
```

### `$filter=not contains(Description,'beta')`

or

### `$filter=not(contains(Description, 'beta'))`

```sql
WHERE Description NOT LIKE '%beta%'
```

### `$filter=startsWith(Name, 'Al')`

```sql
WHERE Name LIKE 'Al%'
```

### `$filter=endsWith(Name, 'son')`

```sql
WHERE Name LIKE '%son'
```

### `$filter=contains(Name, 'son') and Category in ('Books', 'Movies')`

```sql
WHERE Name LIKE '%son%' AND Category IN ('Books', 'Movies')
```

## Support

GraphQL only supports these for SQL, we can start there with REST.

Commencez par src/Core/Models/GraphQLFilterParsers.cs aux lignes 655-701 pour comprendre le comportement existant des opérateurs, puis suivez le parcours jusqu’à l’endroit où les expressions REST $filter sont analysées. Le travail est considéré comme terminé lorsque les filtres REST adossés à SQL prennent en charge in, contains, not contains, startsWith et endsWith, y compris les combinaisons présentées ; vérifiez les exemples documentés par rapport aux réponses REST.
