3.8.0-beta.0

#10887 f8c0b965d Thanks @phryneas! - Add a new mechanism for Error Extraction to reduce bundle size by including
error message texts on an opt-in basis.
By default, errors will link to an error page with the entire error message.
This replaces "development" and "production" errors and works without
additional bundler configuration.
Bundling the text of error messages and development warnings can be enabled by
```
import { loadErrorMessages, loadDevMessages } from "@apollo/client/dev";
if (process.env.NODE_ENV !== "production") {
  loadErrorMessages();
  loadDevMessages();
}
```
#10509 79df2c7ba Thanks @jerelmiller! - Add the ability to specify custom GraphQL document transforms. These transforms are run before reading data from the cache, before local state is resolved, and before the query document is sent through the link chain.
To register a custom document transform, create a transform using the DocumentTransform class and pass it to the documentTransform option on ApolloClient.
```
import { DocumentTransform } from "@apollo/client";

const documentTransform = new DocumentTransform((document) => {
  // do something with `document`
  return transformedDocument;
});

const client = new ApolloClient({ documentTransform: documentTransform });
```
For additional documentation on the behavior and API of DocumentTransform, see the pull request.
