Bun Package Installer does not support bun.lock, the new lock file standard for Bun (starting v1.2

[r4hulp]

Describe the bug

Starting from Bun v1.2.0, the default lock file format changed from bun.lockb (binary) to bun.lock (text-based). The current implementation in BunPackageInstallerLifecycleHook only checks for bun.lockb, which means projects using newer versions of Bun will fail the package installation step.

Regression

Steps to reproduce

1. Create a new Aspire project with Bun support
2. Install Bun v1.2.0 or later
3. Run bun install in your project directory (this will create a bun.lock file)
4. Try to run the Aspire project

The application fails to start with the error:

: No bun.lockb file found in {WorkingDirectory}

Expected behavior

The package installer should:

• Check for either bun.lock (new format) or bun.lockb (legacy format)
• Continue execution if either file exists
• Only throw an error if neither lock file is present
