Issue discovered with `src/main/java/software/aws/mcs/auth/SigV4AuthProvider.java`

[pway99]

Problem

Transforms recipe on the SaaS works fine when running the rewrite-maven-plugin

Expected behavior

Removes UnsupportedEncodingException while the method declaration has a statement which invokes a private method that throws an UnsupportedEncodingException

Example diff

         return Arrays.copyOfRange(challenge, nonceStart, nonceEnd);
     }
 
-    private String generateSignature(byte[] nonce, Instant requestTimestamp, AwsCredentials credentials) throws UnsupportedEncodingException {
+    private String generateSignature(byte[] nonce, Instant requestTimestamp, AwsCredentials credentials) {
         String credentialScopeDate = Aws4SignerUtils.formatDateStamp(requestTimestamp.toEpochMilli());
 
         String signingScope = String.format("%s/%s/%s/aws4_request", credentialScopeDate, signingRegion, CANONICAL_SERVICE);
