[9.0.0] Can't define attributes for repository rules that should only be reserved for build rules

[michaelm-openai]

Description of the bug:

Attributes such as repository_ctx.attr.visibility were removed, but it's not possible to explicitly define an attribute with those names:

Error in repository_rule: There is already a built-in attribute 'visibility' which cannot be overridden

        "visibility": attr.string_list(default = []),
    },
)
