Support svelte.config.cjs file naming

[mcmxcdev]

When trying to run unit tests with SvelteKit, svelte-jester throws Could not find svelte.config.js.

It would be great to have SvelteKit support!

It looks like Cosmiconfig v7 handles .cjs files. I don't think that updating this project's Cosmiconfig dependency is the only change necessary, but it would probably remove the No loader specified for extension ".cjs" error that I'm getting when I try this transform config: transform: { "^.+\\.svelte$": ["svelte-jester", { preprocess: "./svelte.config.cjs" }] }

Actually, I just tried it and { preprocess: "./svelte.config.cjs" } totally works if svelte-jester uses Cosmiconfig v7! The change I'm talking about is here, but it's literally just updating the dependency version.

The other question is what should { preprocess: true } do -- should it look for "svelte.config.cjs" if "svelte.config.js" doesn't exist? And the same for { rootMode: "upward" } -- should it search for "svelte.config.cjs" as well as "svelte.config.js"?

Hey @forrestjacobs thanks for looking into all this! If you can throw a PR my way for this I'm happy to pull it in and release ASAP. The answer to both questions is yes, it should look for both svelte.config.js and svelte.config.cjs.

@mihar-22 sure thing! Just opened one.
