VSCode migration from RubyMine - HELP

We have a large Ruby on Rails started at ROR version 4 (recently upgraded to ROR 7, with Ruby 3.2.1).

-> Now the issue is till date we were using the JetBrains RubyMine with docker-compose setup, RubyMine - docker-compose setup, everything was working fine with rubocop, debugger. gem files navigation, and RubyMines intellisense.

-> Now we are planning to stop the RubyMine subscription and started the migration to VScode.

I'm trying to containerize the setup using VSCodes devcontainer feature with the existing docker-compose.yml file configured exsting. I have successfully setted up the ruby-lsp (from shopify). But when I try to setup Sorbet, I have following confusions and issues,

1. I only wanted the Sorbet's LSP for my project (type checking is not required) - main
2. For sorbet I need the Sorbet's gem to be installed, but I don't want the existing application's Gemfile to be polluted. Therefore I have created another Gemfile under the .devcontainer folder and added required gems.
3. Is solargraph is any way better than sorbet.
4. What is the best way to achieve this requirement?

                "sorbet.sorbet-vscode-extension",
                "KoichiSasada.vscode-rdbg"
            ]
        }
    },

    // Uncomment to connect as an existing user other than the container default. More info: https://aka.ms/dev-containers-non-root.
    // "remoteUser": "devcontainer"

    "workspaceFolder": "/src"
}

This is my devcontainer config, and also each time I want to bundle the gems even though the docker-compose does that.

Please help out.
