feat(svelte): add 'typescript-svelte-plugin' in vtsls globalPlugins

[shubham-cpp]

📑 Description

• Add typescript-svelte-plugin as a global plugin for vtsls. Same as lazyvim/svelte.ts config
• For the vue's config, I've removed the default empty setting for globalPlugins = {},. Because of this if you had community.lua config like below where pack.svelte is above pack.vue this would result in typescript-svelte-plugin not being added.

-- lua/community.lua
---@type LazySpec 
return {
  "AstroNvim/astrocommunity",
  { import = "astrocommunity.pack.svelte" },
  { import = "astrocommunity.pack.vue" }
}

📖 Additional Information

How to verify:

1. git clone --depth 1 https://github.com/AstroNvim/template ~/.config/nvim-astro-demo
2. NVIM_APPNAME=nvim-astro-demo nvim
3. Update the community.lua with following content

-- lua/community.lua
---@type LazySpec
return {
  "AstroNvim/astrocommunity",
  -- you could also put the svelte below vue
  { import = "astrocommunity.pack.svelte" },
  { import = "astrocommunity.pack.vue" },
}

4. Open a svelte project(or create new npx sv create demo-svelte-app --template minimal --types ts
5. Open any .ts file, run :LspInfo and check globalPlugins table has the typescript-svelte-plugin plugin

Review Checklist

Does this PR follow the [Contribution Guidelines](development guidelines)? Following is a partial checklist:

Proper conventional commit scoping:

• If you are adding a new plugin, the scope would be the name of the category it is being added into. ex. feat(utility): added noice.nvim plugin

• If you are modifying a pre-existing plugin or pack, the scope would be the name of the plugin folder. ex. fix(noice-nvim): fix LSP handler error

• Pull request title has the appropriate conventional commit type and scope where the scope is the name of the pre-existing directory in the project as described above

• README is properly formatted and uses fenced in links with <url> unless they are inside a [title](url)

• Entry returns a single plugin spec with the new plugin as the only top level spec (not applicable for recipes or packs).

• Proper usage of opts table rather than setting things up with the config function.

• Proper usage of specs table for all specs that are not dependencies of a given plugin (not applicable for recipes or packs).
