Proposal: Create a feature to install Bun

[duduribeiro]

This PR adds bun as a oficial devcontainers feature.

Bun is an all-in-one JavaScript runtime & toolkit designed for speed,
complete with a bundler, test runner, and Node.js-compatible package
manager.

This feature can be installed in any linux os.

Tested locally with a sample app and it worked fine:

	"features": {
		"./bun/": {}
	},
vscode ➜ /workspaces/vscode-remote-try-go (main) $ bun -v
1.1.4


	"features": {
		"./bun/": {
			"version": "1.0.1"
		}
	},
vscode ➜ /workspaces/vscode-remote-try-go (main) $ bun -v
1.0.1

Hi 👋

We appreciate your Feature contribution, however, the devcontainers/features repo only accepts improvements and bug fixes for the current set of maintained Features.

However, we would appreciate if you could add this Feature in a separate repository of your control. The devcontainers/feature-starter repo has more guidance on self authoring them.

Once you've self authored and if you'd like to share it with the community, we'd recommend adding it to the index. It will make them visible in our supporting tools (like https://containers.dev/templates, Dev Containers Extension, GitHub Codespaces etc).

Feel free to ask any questions/queries along the way, feedbacks are welcome too!
