feat: Update koillection-install.sh to support API usage (#16425)

* feat: Update koillection-install.sh to support API usage

Current config is missing the generation of the SSH keys necessary to create JWT tokens, as well as the Apache config necessary to allow through Authorization headers.

See:
- https://github.com/benjaminjonard/koillection/wiki/manual-installation
- https://symfony.com/bundles/LexikJWTAuthenticationBundle/current/index.html?utm_source=chatgpt.com#important-note-for-apache-users

* fix: missing backslash

* feat: ensure subsequent executions don't replace keys
