[feature request] Add support for the bun package manager

[eelkevdbos]

Executing bunx update-browserslist-db@latest results in the following error:

update-browserslist-db: No lockfile found. Run "npm install", "yarn install" or "pnpm install"

Bun uses a binary lockfile called bun.lockb and at the time of writing has no built-in method yet to update individual packages.

Sure, please send PR.

Just be sure that you are updating all nested dependencies.

I'm working on a draft PR and will post back as soon as I have a working setup.

I need some Bun user to send PR. Here is what you need to do:

1. Add Bun detection here https://github.com/browserslist/update-db/blob/main/index.js#L41-L57
2. Add caniuse-lite latest version extraction here https://github.com/browserslist/update-db/blob/main/index.js#L63-L79
3. Add caniuse-lite update CLI call like this https://github.com/browserslist/update-db/blob/main/index.js#L288-L289
4. Add tests to text/fixtures and call them from test/index.test.js.

Bun support added with 1.1. Thanks to @pornoiya and @kytta.

Note 2 limits:

1. You need to have npm to get latest caniuse-lite version.
2. It will add caniuse-lite to dependencies. https://github.com/browserslist/update-db/issues/42

We created issues in Bun repo to fix these limits.
