Prior to this commit, if a value existed at the specified JSON path but
had an incompatible type, the AssertionError thrown contained a message
stating that the value did not exist (i.e., "No Value at JSON Path"),
which was not only misleading but also technically incorrect.
This commit fixes the error message for such use cases. For example, the
AssertionError thrown in such use cases now resembles the following.
At JSON path "$.name", value <Lisa> of type <java.lang.String> cannot
be converted to type <byte[]>
Closes gh-25480
