updating jackson-core version

[ShyamalaGowri]

shaded jar https://repo1.maven.org/maven2/com/google/cloud/bigdataoss/gcs-connector/hadoop3-2.2.25/gcs-connector-hadoop3-2.2.25-shaded.jar contains CVE PRISMA-2023-0067. (https://nvd.nist.gov/vuln/detail/CVE-2023-0067)
This is because it includes jackson-core (This is required by google-api-client-jackson2)

<groupId>com.fasterxml.jackson.core</groupId>
  <artifactId>jackson-core</artifactId>
  <name>Jackson-core</name>
  <version>2.13.4</version>

I have fixed the CVE by excluding the version that had the vulnerability and added the fix by adding

<groupId>com.fasterxml.jackson.core</groupId>
 <artifactId>jackson-core</artifactId>
 <version>2.15.0</version>

This PR contains the fix for the issue #1221
