fix: apply fixes required for Vite plugin in Astro (#332)

* fix: Use same directory for tmpdir to prevent cross-volume issues

* fix: create and destroy netlify dev server bundle in the same place

gets rid of the plugin-level netlifyDev let, and we no longer need to check
if the middleware doesn't exist

* Remove leading 0. from random file name
