Expose the built in rules when using it programmatically

[ThomasJamesCrawford]

Is your feature request related to a problem? Please describe.

We want to import and use this tool within another js tool, but it seems like the built in rules (e.g. dangerousBreaking, suppressRemovalOfDeprecatedField, ignoreDescriptionChanges, safeUnreachable) aren't exposed even though they're included in @graphql-inspector/core

e.g. we use it like this
import { diff } from "@graphql-inspector/core";

Describe the solution you'd like

Some way to import the pre-made rules

import { diff, rules } from "@graphql-inspector/core";

await diff(schema, schema2, [rules.dangerousBreaking]);

Describe alternatives you've considered

Just copy pasting out the rules

Using the CLI

Additional context

We want to be able to narrow down the set of changes we consider breaking more specifically to allow some to pass, which is why we use it programmatically.
