ci(github): fix type exports in examples/cactus-common-example-server

[ruzell22]

Description

Relates to: #3140

Ignore pattern has been added in tools/custom-checks/get-all-tgz-path.ts in PR #3561 for packages that are having error when running the newly added check in custom-checks to validate exported types being correct so that the job will pass for now.

This ticket is created to fix examples/cactus-common-example-server/hyperledger-cactus-common-example-server-*.tgz and delete it in the ignore pattern right after. For more info about the custom-check log, refer to this github action link:

2. remove the ignore pattern for this specific package in tools/custom-checks/get-all-tgz-path.ts
