[Feature]Final Installation via initialization

[caryyu]

The goal of this ticket is to have a default admin credential in k8s secret (whatever the name is) by first initializing this helm chart without second initialization, in the current approach, there has a manual click/input with more configs on the site to finalize the installation, which's what I want to prevent:

Administration information from installing panel(should be generated/stored into a secret)

• admin credential
• admin email

Proposal Idea:

Via https://docs.gitea.io/en-us/command-line/

• Option 1: A Kubernetes Job
• Option 2: A sidecar-container along with Gitea server

I think Option 1 looks more reasonable and comfortable because of Option 2 will always have an extra container stopped once post-init accomplished.

I made an approach for myself already
