Subject: [PATCH 2/3] Fix nullpointer detected by Spotbugs 4.10.3

Spotbugs 4.10.3 improved detection of NP_NULL_ON_SOME_PATH_FROM_RETURN_VALUE,
which now correctly identifies a potential null pointer dereference in
Challenge62McpController.getServiceAccountAccessToken() at line 322.

Since this is an intentional vulnerability in the WrongSecrets educational
project, add a Spotbugs exclusion filter to suppress this finding rather
than fixing the code.
