prebump hook uses the wrong version

[ecraig12345]

In performBump, the versions in packageInfos have already been bumped, including when the prebump hook is called:

beachball/src/bump/performBump.ts

Line 16 in f0f3f64

await callHook(options.hooks?.prebump, modifiedPackages, packageInfos, options.concurrency);

This contradicts the docs for prebump's version param (though this may be why the full packageInfos param was omitted):

beachball/src/types/BeachballOptions.ts

Lines 343 to 346 in f0f3f64

	* @param name The name of the package as defined in package.json
	* @param version The pre-bump version of the package to be published
	*/
	prebump?: (packagePath: string, name: string, version: string) => void | Promise<void>;

This behavior is definitely wrong but could be a little risky to fix outside a major version, since people may be assuming the incorrect behavior.
