feat: Migrate pnpm to Bun

[wouterlucas]

Migrate pnpm to Bun as a package manager of choice for local renderer development.

Everything works except Docker, which has an issue with wait-port on Bun. It returns a socket and exits with error code 3 while it does work on the host machine. Likely due to not being able to detach the child process for building the preview?

Error:

Failed to start server!

Parking it here, for now.

In order to migrate from pnpm:

1. Remove your node modules
2. Make sure local pnpm lock files are gone
3. Install Bun if you havent already, see (https://bun.sh/)[https://bun.sh/] to get started
4. Run Bun i to install dependencies and start with Bun start

Todo:

• Look into Github action workflow and make sure it works with Bun
• Fix --ci Docker issue with wait-port
