Feature Request: Add Custom Key Mapping Configurations for Vim-Surround

Is your feature request related to a problem? Please describe.
I am currently unable to specify my own combination of keys for the vim-surround plugin within VSCode Vim. This feature is available in Neovim, where I can customize the vim-surround plugin as per my preferences in the Neovim configuration file.

Describe the solution you'd like
I would like the ability to customize the key bindings for vim-surround in VSCode Vim. For instance, in Neovim, I can set a specific key combination for surround like so: vim.g.surround_45 = "{(\"/r\")}". I would like a similar functionality to be available in VSCode Vim, where I can set my own key combinations in the settings or in a dedicated configuration file.

This would be configurable in the vscode settings like this:

"vim.surround": {
  "normalModeKeyBindings": [{"before": "-", "after": "{(\"/r\")}"}],
  "visualModeKeyBindings": [...], // etc
}

Here is a Link talking about how you can benefit from the extra surround features the original plugin has to offer.

Describe alternatives you've considered
A potential alternative could be the ability to import Neovim settings into VSCode Vim. However, I believe that having a dedicated setting within the plugin would provide a cleaner and more streamlined user experience.

Additional context
This feature would enhance the user experience by allowing users to have a consistent vim experience across different editors and platforms. It would also help users who have specific vim workflow preferences to efficiently use the vim-surround plugin within VSCode Vim.

The issue does not identify repository files, tests, or entry points. Start by locating the existing vim-surround handling and VS Code settings definitions, then determine how normal- and visual-mode mappings should be represented. Done means users can configure custom surround mappings in settings and those mappings work in the requested modes.
