test: updated the grpc versioned tests utils to dynamically bind ports to avoid conflicts between cjs and esm tests

[bizob2828]

We started seeing failing versioned tests when running in CI after larger runners. It was always grpc tests with:

# Subtest: should record errors in a transaction when ignoring 
        not ok 1 - No address added out of total 1 resolved
          ---
          stack: >
            bindResultPromise.then.errorString
            (node_modules/@grpc/grpc-js/src/server.ts:569:32)
          at:
            line: 569
            column: 32
            file: node_modules/@grpc/grpc-js/src/server.ts
            function: bindResultPromise.then.errorString
          test: "should record errors in a transaction when ignoring "
          source: |2
                          logging.log(LogVerbosity.ERROR, errorString);
                          deferredCallback(new Error(errorString), 0);
            -------------------------------^
                        } else {
                          if (bindResult.count < addressList.length) {

After looking at the tests I realized we bind to a static port. We never hit this before because the grpc and grpc-esm tests were never run at the same time due to concurrency.

To verify this works locally:

node_modules/.bin/versioned-tests --major -i 2 --all --strict --samples 10 test/versioned/grpc test/versioned/grpc-esm/

Previously, this would immediately fail on one of the 2 test suites because it was trying to bind to the same port.
