chore: removed unused env var in app-proxy (#565)

* feat: add GIT_SSL_CAINFO environment variable for secure Git operations (was already merged in previous pr, but i wanted to merge the template fix)

This change introduces the GIT_SSL_CAINFO variable to specify the
location of the CA certificate for SSL connections, enhancing the
security of Git operations within the app-proxy environment.
Additionally, it removes the WORKFLOW_PIPELINES_WEBHOOKS_TLS_SECRET
variable to streamline the configuration.

* chore: remove GIT_SSL_CAINFO environment variable from container config

This change removes the GIT_SSL_CAINFO variable from the environment
variables defined for the cap-app-proxy container. This adjustment
ensures that the configuration aligns with the current security
standards and practices.
