fix: update vite dep to exclude posthog from pre bundle

[calisio]

Description of the change

Kept getting this error on make dev that was related to node_modules. Even clearing node_modules and re installing dependencies would not fix the issues. The error specified was the following:

frontend-1 | The file does not exist at "/app/node_modules/.vite/deps/chunk-QDIOEQG4.js?v=9698f877" which is in the optimize deps directory. The dependency might be incompatible with the dep optimizer. Try adding it to `optimizeDeps.exclude`.

It seemed to be the pre bundling of posthog, so that was excluded in the vite optimize deps. Let me know if there are any concerns with including this in the vite config.
