Support readOnly + required combination again

[FYamazaki]

I am totally new here. But I found a similar issue at [Support readOnly + required combination|https://github.com//issues/145]
The 4.13.9 has the same issue.

[cdimascio]

there is a test for this that is passing.

test: https://github.com/cdimascio/express-openapi-validator/blob/master/test/read.only.spec.ts#L170-L184
oas spec: https://github.com/cdimascio/express-openapi-validator/blob/master/test/resources/read.only.yaml#L14-L46

please validate your spec/usage against this to ensure its accurate

I tried to clone, build, and test. But I couldn't build it. But any test case for both default and readOnly like this?
{code}
nfProfileChangesInd:
type: boolean
default: false
readOnly: true
{code}

Once complete, you'll have a dev environment setup in the cloud for express-openapi-validator

5. In the terminal, type

npm i && npm run compile && npm test

All the tests should pass.

You can now add it.only(... to the test in the comment above and poke around with the api spec.
