Allow "collection_name" parameter.

[alexsegura]

Hi,

I'm running multiple instances of the same webapp against a unique Typesense server, and I'm using namespaces/prefixes for collection names. For example let's say I have a products collection, there would be collections prefixed by the app name (app_A_products, app_B_products, etc). Also, on my dev environment, I have a specific collection for tests (i.e app_products_test).

All of this is made dynamic by using env vars.

Of course, I would like to use the "generic" name (i.e products) inside my code, while having TypesenseBundle classes target the expected collection.

I noticed there is a collection_name parameter which seems designed for this, but is unused. So I tried to make it work.
Not sure what I did is 100% correct as I'm not an expert in Symfony dependency injection.

As a result, with the following configuration:

parameters:
    env(APP_NAME): "app_A"
    typesense_products_collection_name: "%env(APP_NAME)%_products"

acseo_typesense:
    collections:
        products:
            collection_name: '%typesense_products_collection_name%'
            entity: 'App\Entity\Product'
            fields:
                id:
                    name: id
                    type: primary
                sortable_id:
                    entity_attribute: id
                    name: sortable_id
                    type: int32
                name:
                    name: name
                    type: string
            default_sorting_field: sortable_id

• When calling $collectionManager->createCollection('products') (for example), it actually creates the app_A_products collection
• I have a service typesense.finder.products which actually targets the collection app_A_products
