fix(instance): EoS warning should only display the 5 most relevant types

[Mia-Cross]

For the end of service warning message to be clearer, we should only display the 5 most relevant Instance types, and redirect users to the CLI for the full list. The warning will be displayed as follows :

╷
│ Warning: Your Instance will soon reach End of Service. You can check the exact date on the Scaleway console. We recommend that you migrate your Instance before that.
│ Here are the 5 best options for "ENT1-S", ordered by relevance: [POP2-8C-32G, POP2-2C-8G, POP2-4C-16G, POP2-16C-64G, POP2-32C-128G]
│ 
│ You can check the full list of compatible server types:
│       - on the Scaleway console
│       - using the CLI command 'scw instance server get-compatible-types e957d3cb-8b5a-4881-804b-4ac1b612b3e3 zone=fr-par-1'
│ 
│   with scaleway_instance_server.eos,
│   on endofservice.tf line 14, in resource "scaleway_instance_server" "eos":
│   14:   type = "ENT1-S"
│ 
│ Instance type "ENT1-S" will soon reach End of Service
