KSE-1845: unpin classgraph dependency to use the version defined in common

[janjwerner-confluent]

Description

Unpin version of classgraph dependency to use the version defined in common

Testing done

Describe the testing strategy. Unit and integration tests are expected for any behavior changes.

Reviewer checklist

• Ensure docs are updated if necessary. (eg. if a user visible feature is being added or changed).
• Ensure relevant issues are linked (description should include text like "Fixes #")
• Do these changes have compatibility implications for rollback? If so, ensure that the ksql command version is bumped.

Thanks @janjwerner-confluent for the PR.
PR build failed with the following error:

[ERROR]   The project io.confluent.ksql:ksqldb-parent:7.0.16-0 (/home/semaphore/ksql/pom.xml) has 1 error01:10
[ERROR]   Non-resolvable parent POM for io.confluent.ksql:ksqldb-parent:7.0.16-0: Could not find artifact io.confluent:common:pom:7.0.16-0 in confluent-codeartifact-internal (https://confluent-519856050701.d.codeartifact.us-west-2.amazonaws.com/maven/maven/) and 'parent.relativePath' points at wrong local POM @ line 22, column 13 -> [Help 2]

The error is due to change of range version to pinned versions by Confluent semaphore job.
I have already created a JIRA: https://confluentinc.atlassian.net/browse/KSQL-12349
I am unable to raise a fix because ksql is a public repo and I am unable to push code to the repository.
