express 5-alpha and npm7

[ex1st]

Hi,
We're using "swagger-ui-express": "4.1.6" with "express": "^5.0.0-alpha.8". It works fine for node 14 and npm 6, but after upgrade to node 16 and npm 7 we have caught the error:

npm ERR! code ERESOLVE
npm ERR! ERESOLVE unable to resolve dependency tree
npm ERR! 
npm ERR! While resolving:
npm ERR! Found: express@5.0.0-alpha.8

Can you add express 5 to peerDependencies also?
Thank you!

Prerelease versions are not included in the semver calculation. Until express 5 is released this error will continue.

If you want to go ahead with the install you can npm install --force

Hi @scottie1984 maybe you can remove express from peerDependencies in the next major release? Users can add express to package.json by themselves. Thank you!
