Detect bun as the package manager when using bun.lock

[anurag-roy]

Clear and concise description of the problem

Bun is introducing a text-based lockfile called bun.lock.

At the time of writing this, the feature is in the canary version, but will soon land in stable and supposedly will be the default after v1.2.

package-manager-detector does not detect bun as the package manager when using bun.lock

Suggested solution

Add a new line in src/constants.ts

export const LOCKS: Record<string, AgentName> = {
  'bun.lockb': 'bun',
+ 'bun.lock': 'bun',  
  'deno.lock': 'deno',
  'pnpm-lock.yaml': 'pnpm',
  'yarn.lock': 'yarn',
  'package-lock.json': 'npm',
  'npm-shrinkwrap.json': 'npm',
}

And of course add new tests for the above.
