create-svelte: include globals.d.ts in tsconfig

Apparently globals.d.ts was being ignored entirely. Whoops.

Perhaps we should put it in src for better organization and include src/**/*.d.ts?

Also, it seems more common to call it global.d.ts. I'm guessing that doesn't really matter for the most part, but might make it easier for people who don't know what it is to search and find results online

+1 on putting it inside src. +1 on adding src/**/*.d.ts. Name - I don't care 😄

If I recall next js puts the d.ts in src, seems pretty reasonable to think of it as a source file to me

Moved to /src/global.d.ts as recommended above.
