LinksPreview::Ability to remove the attached link

[RomaricMourgues]

Describe the solution you'd like
Right now links attachments are created next to messages that contains a link. Like on Slack, I would like to be able to remove the link using a small "x" button next to the attachment which appear on hovering the attachment.

Additional context
In order to implement this we will:

• Create and document the new DELETE /companies/{company_id}/threads/{thread_id}/messages/{message_id}/links/:url_with_encode_uri endpoint to document in Messages operations in https://www.notion.so/linagora/Rest-APIs-232eb8e51c3743ccbb7aa3534a5a7db9

• This endpoint will call a service in src/services/messages/services/messages-operations.ts and will remove any link attachment to the message with the same url

• Only the owner of the message can do this operation so a rule must be added to compare the context user to the message creator.

• The update must be broadcasted via websockets (using this.threadMessagesService.onSaved(message, { created: false }, context);)

• On frontend, we will add the api-client function in src/app/features/messages/api/message-api-client.ts

• On frontend, we will add this operation to src/app/features/messages/hooks/use-message.ts as removeLink(url: string) accessible from the return of the hook

• On frontend, we will add the "x" using feather icons as usual
