Add support for typescript "Go to Source Definition"

No response

Describe the new feature

It would be useful, since the default 'go to definition' jumps to a .d.ts file and there is no easy way to go to the source .js file.

There is already a plugin in the pack that offers this functionality: https://github.com/yioneko/nvim-vtsls?tab=readme-ov-file#commands

But it doesn't have any keybindings attached to the offered commands.

---@type LazySpec
return {
  "AstroNvim/astrolsp",
  ---@type AstroLSPOpts
  opts = {
    mappings = {
      n = {
        gs = {
          function() require("vtsls").commands.goto_source_definition() end,
          desc = "Goto Source Definition",
          cond = function(client) return client.name == "vtsls" end,
        },
      },
    },
  },
}

Now just need to create a PR for this :)
If someone else wishes to do it, go for it.

Oh that cond thing is smexy. I tried to add an autocmd, but this seems much cleaner

Just some context as to why I researched about this feature.

Here https://github.com/OrJDev/trpc-limiter/blob/923ae1e6c6122cc60f2cb7aebcbd99717ade57ad/examples/nextjs-redis/src/server/api/trpc.ts#L82 can see defaultFingerPrint which has this implementation https://github.com/OrJDev/trpc-limiter/blob/923ae1e6c6122cc60f2cb7aebcbd99717ade57ad/packages/core/src/index.ts#L96 doesn't provide any documentation as to how it functions.

The transpiled d.ts type only shows the function signature, which is pretty useless in this context. And only jumping to the source .js file you can understands that it reads a specific request header for an ip address.
