Proposal: Add svelte-check and vscode recommendation

[dummdidumm]

At the moment, svelte-check and the "hey, install this VSCode extension"-notification are only applied after using the "setup TypeScript" script. I think both of these are valuable also to non-TS-projects, so maybe add them to the base template?

I think svelte check is an easy yes from me and I'd merge that without discussion

I feel a little mixed on the vscode one, but I wouldn't block it 👍

I think the vscode recommendation is arguably more helpful than the the svelte-check one for non-TS users. At least until other editors make use of the language server to gain special powers.

I feel like the notification about svelte-check would be comparable to notifying about a linter. If people are new to TS, Svelte, or development in general then it could be confusing without any context.

Sooo ... this means one upvote and half a downvote each on "add svelte-check" and "add VSCode extension recommendation"? 😄
