error when invalid args passed to `svelte-check`

[DetachHead]

Description

i was trying to run svelte-check -p src/tsconfig.json and couldn't figure out why it wasn't working, because i forgot that the argument is actually called --tsconfig (i was mixing it up with tsc which uses -p)

Proposed solution

throw an error if an unrecognized argument is passed to svelte-check
