Support wildcard for version

[owjs3901]

If package.json has a packageManager property and set any string to the version of pnpm setup action, it raises an error. However, the star sign(*) means to allow any version. So, If * is set as the version of the pnpm setup action, the action should select the version in package.json.

Is this supported by corepack?

@zkochan Yes, It works

No, that command will resolve the package manager to an exact version and write an exact version to package.json. The packageManager field currently only works with exact versions.
