Epic: Vim as an explicit IDE preference

[loujaybee]

We currently have access to workspaces via SSH, however adding Vim would make it a first-class citizen as part of the Gitpod experience. Alongside this we should consider what we can do to ensure things like dotfiles are also setup, and that workspaces potentially already load with vim + other similar tools such as tmux. This would support experiments such as #6707 where vim configuration can be presented to the user as part of onboarding.

Relates to:

• Add tmux and neovim chunks and use them in the full image workspace-images#825
• Change default directory when SSH to workspace #9377
• Epic: Improved support for user-defined shells (e.g. fish / zsh, etc) #10105
• SSH as the default editor #17928

@loujaybee I haven't researched this in depth about this yet, but here are some early designs on what I had in mind for #7713 (comment). Cc @josepjaume
