## Context
LabelIdentifier and ImageIdentifier are metadata info attached to
objectMetadata that are used to display a record in a more readable way.
Those columns point to existing fields that are part of the object.
For example, for a relation picker of a person, we will show a record
using the "name" labelIdentifier and the "avatarUrl" imageIdentifier.

Currently, the FE has a specific logic for company and people objects
and we have a way to update this value via the API for custom objects,
but the code is not flexible enough to change other standard objects.
This PR updates the WorkspaceEntity API so we can now provide the
labelIdentifier and imageIdentifier in the WorkspaceEntity decorator.
Example:
```typescript
@WorkspaceEntity({
standardId: STANDARD_OBJECT_IDS.activity,
namePlural: 'activities',
labelSingular: 'Activity',
labelPlural: 'Activities',
description: 'An activity',
icon: 'IconCheckbox',
labelIdentifierStandardId: ACTIVITY_STANDARD_FIELD_IDS.title,
})
@WorkspaceIsSystem()
export class ActivityWorkspaceEntity extends BaseWorkspaceEntity {
@WorkspaceField({
standardId: ACTIVITY_STANDARD_FIELD_IDS.title,
type: FieldMetadataType.TEXT,
label: 'Title',
description: 'Activity title',
icon: 'IconNotes',
})
title: string;
...
```
