feat: add eslint rule for enforcing WorkspaceService naming convention (#6308)

### Description

This PR introduces a custom ESLint rule named
`inject-workspace-repository`. The purpose of this rule is to enforce
naming conventions for files and classes that use the
`@InjectWorkspaceRepository` decorator or include services ending with
`WorkspaceService` in their constructors.

### Rule Overview

The new ESLint rule checks for the following conditions:

1. **File Naming**:
- Only file ending with `.service.ts` or `.workspace-service.ts` are
checked.
- If a file contains a class using the `@InjectWorkspaceRepository`
decorator or a service ending with `WorkspaceService` in the
constructor, the file name must end with `.workspace-service.ts`.

2. **Class Naming**:
- Classes that use the `@InjectWorkspaceRepository` decorator or include
services ending with `WorkspaceService` in their constructors must have
names that end with `WorkspaceService`.

### How It Works

The rule inspects each TypeScript file to ensure that the naming
conventions are adhered to. It specifically looks for:

- Constructor parameters with the `@InjectWorkspaceRepository`
decorator.
- Constructor parameters with a type annotation ending with
`WorkspaceService`.

When such parameters are found, it checks the class name and the file
name to ensure they conform to the expected patterns.

### Example Code

#### Valid Cases

1. **Correct File and Class Name with Decorator**:
    ```typescript
    // Filename: my.workspace-service.ts
    class MyWorkspaceService {
      constructor(@InjectWorkspaceRepository() private repository) {}
    }
    ```

2. **Service Dependency**:
    ```typescript
    // Filename: another.workspace-service.ts
    class AnotherWorkspaceService {
      constructor(private myWorkspaceService: MyWorkspaceService) {}
    }
    ```

#### Invalid Cases

1. **Incorrect Class Name**:
    ```typescript
    // Filename: my.workspace-service.ts
    class MyService {
      constructor(@InjectWorkspaceRepository() private repository) {}
    }
    // Error: Class name should end with 'WorkspaceService'.
    ```

2. **Incorrect File Name**:
    ```typescript
    // Filename: my.service.ts
    class MyWorkspaceService {
      constructor(@InjectWorkspaceRepository() private repository) {}
    }
    // Error: File name should end with '.workspace-service.ts'.
    ```

3. **Incorrect File and Class Name**:
    ```typescript
    // Filename: my.service.ts
    class MyService {
      constructor(@InjectWorkspaceRepository() private repository) {}
    }
    // Error: Class name should end with 'WorkspaceService'.
    // Error: File name should end with '.workspace-service.ts'.
    ```

4. **Incorrect File Type**:
    ```typescript
    // Filename: another.service.ts
    class AnotherService {
      constructor(private myWorkspaceService: MyWorkspaceService) {}
    }
    // Error: Class name should end with 'WorkspaceService'.
    // Error: File name should end with '.workspace-service.ts'.

    ```

5. **Incorrect Class Name with Dependency**:
    ```typescript
    // Filename: another.workspace-service.ts
    class AnotherService {
      constructor(private myWorkspaceService: MyWorkspaceService) {}
    }
    // Error: Class name should end with 'WorkspaceService'.
    ```

### First step

This rule is only a warning for now, and then we'll migrate all the code
that need to be migrated and move from `warn` to `error`.

Fix #6309
