What is the current behavior?

Issue Number: N/A

What is the new behavior?

@apollo/server@v5 is now supported, along with as express@v5

Does this PR introduce a breaking change?

• Yes
• No

An additional dependency is introduced - @as-integrations/express5; not an API breaking change, but projects using this package will have to install the new dependency. I'm happy to update the docs if this gets approved.

Other information

Technically both express@v4 and express@v5 are supported by @apollo/server@v5, but they require separate dependencies - either @as-integrations/express4 or @as-integrations/express5.

Considering that @nestjs/platform-express is on v5, I used v5 here as well.
