[12.x] Fix invalid docblock

[tm1000]

This fixes an invalid doc block that was introduced in #55916. Because there's a hanging parentheses Psalm errors with the following:

Uncaught Psalm\Exception\DocblockParseException: Closure(\Illuminate\Bus\Batch, \Throwable|null): mixed)|(callable(\Illuminate\Bus\Batch, \Throwable|null): mixed) is not a valid type: Invalid string Closure(\Illuminate\Bus\Batch, \Throwable|null): mixed)|(callable(\Illuminate\Bus\Batch, \Throwable|null): mixed)

Ok so now the linter fails with Template type TParam of method Illuminate\Bus\PendingBatch::allowFailures() is not referenced in a parameter.. either way the original is wrong because it has an extra parentheses. Now that its fixed I assume its showing a new error as a result

Edit: Fixed by removing the conflicting php native types in favor of the docblock itself
