Add support for bun as a webapp package manager (#800)

This is working off pull request "[Add support for pnpm as a webapp build tool. #767](https://git.vdb.to/cerc-io/stack-orchestrator/pulls/767/files)" that adds `pnpm` package manager support for `nextjs` & `webapps`.

`bun` default build output directory (defined as `CERC_BUILD_OUTPUT_DIR`) is `dist` which should already be handled with `pnpm` support in the previously mentioned [pull request](https://git.vdb.to/cerc-io/stack-orchestrator/pulls/767/files)

Installing `bun` using `npm` following our previous `pnpm` installation

```zsh
npm install -g bun
```

We'll be using `bun` as a package manager that works with `Node.js` projects as defined in bun's [docs](https://bun.sh/docs/cli/install)

> The bun CLI contains a Node.js-compatible package manager designed to be a dramatically faster replacement for npm, yarn, and pnpm. It's a standalone tool that will work in pre-existing Node.js projects; if your project has a package.json, bun install can help you speed up your workflow.

To test `next.js` apps using `node.js` and compatibility with all four packager managers -- `npm`, `yarn`, `pnpm`, and `bun` -- use the branches of snowball's [nextjs-package-manager-example-app](https://git.vdb.to/snowball/nextjs-package-manager-example-app) repo: `nextjs-package-manager/npm`, `nextjs-package-manager/yarn`, `nextjs-package-manager/pnpm`, `nextjs-package-manager/bun`.
