Reproduction steps

• Create a package where the package.json's bin field points to a directory
• Add this package as a dep in another package
• Run pnpm install

Describe the Bug

Invalid values in the bin field of package.json fails to install with EISDIR: illegal operation on a directory, read. Afaik packageExtensions can not be used to "fix" this field.

Expected Behavior

Invalid values in the bin field are ignored/warned and do not fail the installation (like yarn and npm).
