Subject: [PATCH] test(nextjs): Run the source map upload e2e test on Bun

Adds Bun variants for the Turbopack and the webpack build of
`nextjs-sourcemaps`. They build with `bun --bun run build`, so Bun runs
`next build` and the upload. The assert script checks the runtime in the
User-Agent of the `sentry` CLI requests, so a variant fails when another
runtime does the upload.
