feat: add default exclude to tsconfigs

[Princesseuh]

With TS 5.5, we can now do this in our default templates. For users using lower versions, it just won't work. For users using any other dist dir, they'll want to update their own exclude anyway, overriding this. If someone has changed the default output, and has a dist folder that is not supposed to be ignored by TS (???) they can also override this in their own tsconfig.json.

LGTM but 2 questions:

• do we need a changeset for that? (i guess so)
• should we update the include as well? with ["${configDir}/.astro/types.d.ts", "${configDir}/**/*"]

[Princesseuh]

Yeah, we can do the include as well, should be fine with the **/*, but I'll test it to make sure!
