getSession() does not listen to the SessionProvider baseUrl

[rcannood]

Hi @OrJDev ! Thanks for creating a solidstart authjs package!

I'm running into an issue, where passing a baseUrl to the SessionProvider doesn't seem to affect a part of the code.

---

In my app.tsx, I'm passing a baseUrl to the SessionProvider:

              <SessionProvider baseUrl={getServerBaseUrl()}>
                <Layout>{props.children}</Layout>
              </SessionProvider>

However, when trying to authenticate on Deno Deploy, I get:

@auth TypeError: error sending request for url (http://localhost:3000/api/auth/session): client error (Connect): tcp connect error: Cannot assign requested address (os error 99): Cannot assign requested address (os error 99)
    at async mainFetch (ext:deno_fetch/26_fetch.js:177:12)
    at async fetch (ext:deno_fetch/26_fetch.js:423:7)
    at async A$b (file:///src/server/index.ts:34473:13)

    at async s (file:///src/server/index.ts:34459:23)

I have a feeling that this is because the following code does not listen to the sessionprovider's baseUrl:

mediakit/packages/auth/solid/src/client.tsx

Line 238 in 9f1054b

const res = await fetch(getUrl(`${getBasePath()}/session`), reqInit)

Because getUrl only looks at AUTH_URL_INTERNAL, AUTH_URL, VERCEL_URL, all of which are undefined in my case.
