HierarchicalUriComponents::getPort() throws NumberFormatException with invalid port in URI

[Jackson-S]

Affects: 5.3.18

---

HierarchicalUriComponents::toUri() throws java.lang.NumberFormatException instead of the expected IllegalStateException when provided with a URI of the format https://x.com:string.

The underlying issue is that HierarchicalUriComponents.getPort() invokes Integer.parseInt() which throws the NumberFormatException.

Thus, invocations of getPort(), toUri(), toUriString(), and toString() are all affected.

This has been addressed in 5.3.x and main.
